What Equipment Is Needed For Aquaponics?

What Equipment Is Needed For Aquaponics


Having a tank is the first and most important part of an aquaponics setup. The size and type of tank you need will depend on the fish and plants you decide to grow. Things to consider when choosing a tank include the fish species you want, the plant types, and the size of the plants. Different types of tanks can also provide a decorative aspect to the setup, making it a beautiful addition to any home.

Let’s look at the different types of tanks available for aquaponics:

Choose A Tank Size

When deciding on a tank for your aquaponics system, it’s important to consider the size based on the number of fish and plants you want to cultivate. In general, for one square foot of grow bed, you need about 20 gallons of water in the tank. The amount may vary according to species, so do research on preferred conditions for each type of fish. Checkout more about aquarium tank.

The ideal tank should meet two criteria: be light enough to move and carry enough water volume that supports appropriate fish population and plant growth. You’ll have a few options when it comes to choosing your tank:

  • Plastic Storage Bins: These are an affordable option and come in various sizes – typically only up to 50 gallons or so. Because these bins are made with plastic, they can become porous over time if heated and exposed to UV rays, which increases the likelihood of leaks. Additionally, many plastic tanks lack adequate filtration systems; however, there are some pre-made systems available with built-in filters.
  • Pond Liners: This type of reservoir holds more water than storage bins while being lightweight and easy move around when gardening season ends. Choose from an assortment of materials such as rubber or PVC liner system that’s irregularly shaped with sharp corners for extra mobility when the system needs to be taken apart. However, be aware that using anything other than a rubber liner exposes you to the risk of gas buildup leaking into your system due to C02 rising from decomposing organics within the water column.
  • Stock Tanks: These metal containers can range anywhere from 30 gallons up 600+ depending on how large your aquaponic garden will be. These are typically made out of metal with galvanized steel as one popular option although they have been known rust if not treated properly over time causing leakage issues within the system itself. Stock tanks also provide great filtration which is additional bonus when looking into this option since it has convenience built-in!

Choose A Tank Material

The tanks used for aquaponic setups come in many different forms and materials. Selecting the right material is an important consideration, as it can heavily influence water quality and temperature.

  • Glass Aquariums – An aquarium usually has low thermal mass meaning the temperature of the water is easily influenced by changes in the air temperature of your environment. They are also expensive and not appropriate for larger aquaponic systems because of their fragility.
  • Plastic Storage Containers – Plastic storage containers, such as those made from HDPE, are popular choices for many aquaponics systems. These tanks are inexpensive and readily available, but do require some modification to suit your particular application as standard household plastics may contain hazardous chemicals that could leach into your water. Additionally, proper insulation needs to be taken into consideration to maintain a consistent temperature level within a given system.
  • Stocking Tanks – Stocking tanks are typically large custom built stainless steel or concrete vats with sophisticated filtration systems built in. They usually have an impressive thermal mass meaning they can store heat over time instead of quickly releasing it during cold nights or days – which allows you to better control temperatures within an aquaponic system and reduce fluctuation in tank temperatures significantly. Stocking tanks typically use a gravity filter or other type of filtration system instead of pumps, allowing them to be powered by solar energy if desired. They often take up less space than HDPE containers do, making them ideal for surface-level applications such as rooftop gardens or small yard spaces.


When building an aquaponics system, a pump is essential for supplying water to the tank. A good quality pump will ensure that the water is flowing properly, and that all of the nutrients are getting to the plants and fish. With the right pump, plants can get the oxygen they need without having to be turned on and off throughout the day.

Additionally, the pump will help to create circulation of the fish waste throughout the tank, allowing the plants to benefit from the fish’s waste.

Choose A Pump Type

Third on the list of equipment needed for aquaponics is the pumping system. The key to successful aquaponics is maintaining a steady stream of water, so finding a quality pump is essential. Depending on the scope of your project and its staging, there are several types of pumps to choose from:

  • Submersible (Inline) Pumps – These are submerged beneath the surface and are most commonly used in large-scale aquaponic systems. They pump water vertically, drawing from an outside source into a massive tank below the structure or directly from the source above. Submersible pumps are quite powerful but can be quite loud; however, due to their size and additional installation costs these pumps tend to be relatively expensive.
  • Sump Pumps – Sump pumps are typically used in smaller scale systems as they work well for domestic sized units and can easily be attached or disconnected with minimal setup time. They operate by sucking up water from one end, such as a bucket or pond, then transferring it to another location through either horizontal or vertical displacement, depending on how you choose to set up your system.
  • Centrifugal Pumps – Relatively inexpensive centrifugal pumps operate by using blades that spin inside a pipe to transfer water between locations at different heights and distances apart. Although they aren’t as efficient as inline or sump pumps they get the job done in small scale operations with minimal setup time required due to their plug-and-play installation process.
  • Diaphragm Pumps – Diaphragm pumps act like mini vacuums; they have suctioned cups that draw incoming flows of water into an internal chamber and then pulse outwards using pressure generated by kinetic energy within that same chamber – leading most frequently for intermittent duty purposes. These type of pumps don’t require power sources such as electricity but do require manual labor in order stay operational; making them primarily suitable for non-automated areas where consistent upkeep is necessary.

Choose A Pump Size

When choosing a pump size for your aquaponics system, it is important to consider the volume of water, the type of components you have connected, and the recommended flow rate for most system designs. Generally speaking, a larger pump provides more control over flow rate and pressure while offering a greater range of adjustable speeds with which you can match the needs of your system.

There are two main types of pumps used in aquaponics: DC (direct current) and AC (alternating current). The type you choose will depend on your power source, the specific demand for flow rates in your system’s design, as well as how much energy efficiency you require from your operation. Considerations when selecting a pump include:

  • Size – Knowing the head height (Ft.) and gallon per minute output requirements necessary for proper pumping;
  • Cost – Establishing a budget that defines what is affordable;
  • Installation Speed – Deciding whether to go with wired versus wireless or inline submersible models;
  • Maintenance Needs – Understanding how maintenance should be handled based on manufacturer’s guidelines.

In addition to this information, consult any guidelines specific to certain parts of the system such as UV sterilizers. UV sterilizers may operate optimally around 10-30 GPM so this should factor into your decision when selecting a pump size. Research relevant resources such as forums specific to aquaponics prior to purchasing any components or materials related to your build so that you make an informed decision on what best meets the needs of your particular project.


In an aquaponics system, a growbed is a crucial piece of equipment. It is a container where plants are grown, typically filled with an inert growing medium such as gravel, clay pellets, expanded clay or coconut coir. The growbed provides physical support for the plants and is where they will absorb nutrients from the water, as it cycles through the system.

The size and type of growbed depend on the type of aquaponics system and the type of plants you will be growing. Let’s look at how to choose the right growbed for your aquaponics setup.

Choose A Growbed Size

When determining the size of the growbed you need for an aquaponics system, many factors come into play, such as the types of fish, plants and other aquatic life that exist in the system. Additionally, care should be taken to ensure that all components of an aquaponics set-up – filtration, pumps and other elements – are properly sized to handle the amount of water within the system.

Generally speaking, there are three size options to choose from when selecting a growbed for an aquaponics setup:

  • Small (10-20 Gallons): This size is suitable for smaller aquariums systems or environments where space may be limited. A small growbed will house species such as guppies or tilapia comfortably.
  • Medium (30-50 Gallons): Medium sized growbeds are appropriate for larger aquarium systems with greater efficiency requirements such as bass or perch breeding. For optimal efficiency, multiple medium sized beds should be used in conjunction with one larger staging bed.
  • Large (60+ gallons): Large growbeds are necessary in order to support a successful commercial operation and/or accommodate larger fish species such as salmon or koi carp. The additional volume requirements of large beds can help prevent oxygen depletion and nitrogen buildup within the water column.

In any case, it is important to properly research your aquaponic operation prior to setting up any components in order to ensure a healthy environment for all plants and aquatic life contained within your system.

Choose A Growbed Material

When it comes to selecting a type of growbed for an aquaponics system there are many options available; from ready-made plastic manufacture beds, through to recycled materials and various types of ceramic or fibreglass modules.

The Growbed material should be non-toxic and inert with respect to pH, and should make for easy root penetration. It should also be able to withstand harsh conditions such as temperature fluctuations, floods or droughts, heavy plant stress and bacteria attack.

When selecting a material into which you will place your plants there are several factors to consider:

  • Cost – If a greater initial cost is payable upfront then more durable methods such as wood may be the best option.
  • Materials Used – Some materials can cause leaching of toxic substances over time, especially if they come into contact with water frequently (i.e., plastic).
  • Level Of Maintenance Required – Some materials require more maintenance (cleaning, repairs etc.) than others in order to maintain the integrity of the system.
  • Sizing – Depending on the size of your system different kinds of growbeds can be used accordingly; large scale systems may require specialised design elements such as steel reinforcements or modular plastic panels while smaller scale systems have greater flexibility in terms of dimensions.

There is no single “best” option when it comes to selecting material for your aquaponics growbed – some common choices include ceramic beds, fibreglass beds, PVC pipes and wooden troughs/barrels/rafts but it all depends on the objectives you have and what fits within your budget

Grow Media

Grow media is the material in which your plants will grow in an aquaponics system. Common grow media include expanded clay pebbles, rockwool, and coarse gravel. It’s important to choose a grow media that is lightweight and porous, allowing for even water distribution and easy plant root growth.

Let’s look at some of the most popular types of grow media in aquaponics:

What Equipment Is Needed For Aquaponics

Choose A Grow Media Type

Aquaponic systems use media to provide physical support and surface contact to beneficial bacteria that are vital to the success of the system. Grow media also helps with anchoring plants, providing and aeration and allowing good water flow through the system. Choosing the right type of media can make all the difference in helping your aquaponics system thrive. Here are some popular types of media commonly used in aquaponics systems:

  • Growstones – Not actually stones at all! These are manufactured from recycled glass, nutrients and organic compounds to help create a highly porous grow atmosphere for plant life. Its numerous air spaces allow important oxygen transfer from the water source or pump into roots feeding plants.
  • Pea gravel – A popular choice for many aquaponic systems, it is heavier than other options so it doesn’t float when liquid levels exceed a certain point, keeps its form when taken out of the tank, does not compact over time and provides a great supporting environment for bacteria growth.
  • Lava Rock – Another process-made product that is composed of volcanic rocks melted down into small pieces suitable for grow beds or integrated into stand-alone units with high strength deaerating pumps placed outside of fish tanks or ponds. It’s lightweight nature allows easy transport but can easily float without anchor support if care is not taken while adding liquids to tanks, basins or ponds.
  • Pumice Stone – Pumice is created by volcanic activity which then gets ground down breaking up its lava structure creating gaps and an environment ideal for bacteria growth whilst still offering a lightweight solution that won’t sink quickly like pea gravel or lava rocks may do during heavy liquid levels application periods in tanks, basins or ponds where this kind of grow chamber may be used regularly.

Choose A Grow Media Size

When searching for the best grow media for your Aquaponics project, you will want to consider the size of each individual piece. Ideally, it should be small enough to ensure that water can pass through between the pieces and not clog or jam up your filter system. Choosing a material that is too large can lead to decreased oxygen availability and slow water flow performance.

Common media sizes range from 0.25” – 2” in diameter but specific sizes may vary depending on the type of Aquaponic system you are using.

Smaller particles usually tend to fill up faster, leading to less water flowrate and eventually decaying in an anaerobic environment which produces high levels of ammonia due to lack of oxygen (a toxic molecule to fish in excess). With this said, choosing a larger grow media is usually best; as long as its pieces are evenly spread out and not packed too tightly together.

The most common materials used include expanded clay pellets, river rock, crushed coral, perlite, pumice stone with other materials also available on the market today. Each has their own set of pros and cons so careful evaluation must be done when committing to one medium over another for an Aquaponics project.

Water Treatment

Water treatment is an important aspect of aquaponics, as it helps to remove toxins, debris, and other substances from the water, making it suitable for the fish and plants. As such, any aquaponics system needs to have some water treatment equipment included in it. This typically includes items such as water filters, pumps, air stones, and other components.

Let’s take a look at some of the most common water treatment equipment used in aquaponics systems:

Choose A Water Treatment System

When setting up an aquaponics system, it is important to choose a water treatment system that is tailored to the needs of your operation. Depending on the type of fish and plants you will grow, as well as the size of your system and amount of water used, you may need different equipment than what another setup would require.

There are several types of water treatments systems used in aquaponics. In general, these treatments help keep your water clean and safe for the fish, plants, and environment. It is important to consult with an experienced professional about the most suitable treatment for your particular situation.

  • Natural Filtration Systems that use gravity filtration or mechanical filters which can be used to remove solid particles before they reach the grow beds. These filtration systems often come with an air pump to help aerate and oxygenate the water as well as facilitate chemical breakdowns such as nitrification and denitrification.
  • Biological Filtration Systems which use live bacteria cultures like nitrosomonas or nitrobacter to break down waste materials into ammonia, nitrite and eventually into harmless nitrates available for uptake by plants in the grow beds. Aeration helps with this process as it increases solubility and availability of nutrients in the grow bed so they can be more readily taken up by plants’ roots.

You may also need other equipment such as pumps, heating elements or UVC lights for disinfection depending on your specific situation. In some cases ultraviolet lighting can be used instead of chemical dosing for algae control or toxin removal from water sources when necessary. The best way to determine what equipment you need for a successful aquaponic system is by speaking with a qualified expert familiar with such systems who can advise you on what suits your needs best based on experience.

Choose A Water Treatment System Size

When it comes to setting up an aquaponic system, one of the major factors to consider is your water treatment system size. The right size will ensure that your water is clean, healthy and safe for your fish and plants. Here are a few things to consider when choosing a water treatment system for your aquaponic ecosystem:

  1. Size: When deciding on a treatment system size, you need to consider the amount of fish, plants and other aquatic life you plan on having in your aquaponic ecosystem. If you plan on having large amounts of fish or lots of other aquatic creatures living in the tank, then you may need to go with a larger system than if you were just starting out.
  2. Cost: You also need to consider how much money you’re willing to spend on a water treatment system for your aquaponic setup. Sad internal filtration systems are relatively inexpensive but they don’t always provide the same level of efficiency as an external filter or even a UV light sterilizer, which can be more costly but provide higher water quality levels overall.
  3. Maintenance/Efficiency: Some external filtration systems are more efficient than others as well as easier to maintain, so it’s important to do some research before investing in one over another. Make sure that the filtration and maintenance tasks are something that you will easily be able to manage over time without too much hassle or risk of harm coming to the ecosystem inhabitants due to poor maintenance practices.

Overall, considering all these factors when selecting a water treatment system strategy will help ensure that both fish and plants have all the necessary nutrients available for photosynthesis and growth needs while eliminating any detrimental toxins or contaminants from contaminating their environment’s habitats etc..


Lighting is one of the most important pieces of equipment for an aquaponics system. It is necessary for photosynthesis, which is the process of plants converting light into energy. There are many different types of lighting available, including LED, fluorescent, incandescent, and halide lights.

Let’s explore what type of lighting would be best for an aquaponics system:

Choose A Lighting Type

Regardless of aquaponics set-up type and whether the system is outdoors or indoors, providing plants with sufficient light is an essential factor for their growth and production. To accomplish this, various types of lighting can be used in the system. Choosing which option to implement will be largely dependent upon budget and other variables such as space constraints, amount of heat the particular system can withstand, etc.

The different types of lighting options to consider using in an aquaponics set-up are: High Pressure Sodium (HPS), Metal Halide (MH), T5 & T8 Fluorescent with Electronic Ballast, LED Grow Lights & Compact Fluorescent (CFL). Utilizing one or a variety of these lighting systems in an aquaponics set-up will provide plants with light in sufficient amount and quality for photosynthesis.

In order to make an informed selection on which type of lighting system to construct or purchase for your aquaponics set-up, it is important to understand the pros and cons associated with each option as listed below:

  • High Pressure Sodium (HPS): This type of grow light gives a ‘warm’ light output that mimics natural sunlight during evening hours; however therefore does not provide much illumination during normal daylight hours. They also generate large amounts of heat so cooling systems may need to be incorporated into their use if built into a closed system environment.
  • Metal Halide (MH): MH lights give off intense yet balanced spectrum white light; however they also create large amounts heat which makes then inefficient users of energy when used in a closed loop environment meaning more energy costs than other options available.
  • T5 & T8 Fluorescent With Electronic Ballast: These types of lights offer good coverage over growing area while utilizing minimal electricity per unit compared to other types; consequently they require some rewiring compared to traditional bulbs if incorporating them into existing hauling structures if physically supporting them is not an easily accessible option meaning installation costs could be raised considerably when building from scratch. They also come in sizes that fit directly underneath grow beds for further methods for ease of implementation but again at a cost determined by physical room constraints.
  • LED Grow Lights: LED grow lights produce no heat making them well suited for use close up wetlands without causing overheating problems while competing against natural lightning sources outside which could result in decreased capability over time even though costing approximately 6 times higher than its existing counterparts used by many growers today given their long life span before needing replacement bulbs exchanged or replaced altogether due obviously supplies versus demand related pricing constraints due their emergence on market so recently; diminishing cost over time as manufacturing becomes further streamlined accordingly as technology advances favoring further future market penetration scenarios overall regardless indoor or outdoor containment solutions existent on point discussed earlier up this page being that efficient operation currently subject under scrutiny still in its infancy ultimately alleviating concerns by expanded availability shortly once technological issues have been rectified satisfactorily industry wide otherwise decentralized setup provides excellent alternative solutions best case scenarios since complete subsections could potentially developed from just simple infrastructural changes additional more sophisticated grow sites subsequently achieving highest yields theoretically possible independent research capacity home region ensuring most favorable sustainability indices regarding H2O consumption bacterial counts crop outputs etc but standardization key make sure research done totally reproducible bona fides all stakeholders operations question clear forthwith information conditions ensure compliance tech specs required related opinion entrepreneurship culture general people background thereof details follow interviews necessary describe markets affect region possible.

Choose A Lighting Size

When choosing a lighting system for your aquaponics set up, you should consider a few factors. Firstly, light controls the growth and health of aquatic plants. Different species of plants require different amounts of lighting and each type of bulb produces a different spectrum of light, so making sure you select an appropriate and energy-efficient light is key.

The wattage size and number should be determined according to the size of your grow bed and water tank. When choosing your number of lights, it is important to have the right ratio between light intensity (measured in watts) and area covered by the plants (measured in square feet). Typically, a 1000-watt system is ideal for up to 250 square feet crop space, while two lights around 800-watts are good for up to 120 square feet.

Finally, aquarium LED Lighting Systems are recommended as they provide energy efficiency with good illumination reproducing what natural sunlight can offer. The type of bulb used also plays a role in how much energy you use; for example fluorescent lights are more energy efficient than incandescent bulbs but provide less concentrated lighting and is suitable only for larger areas.

When considering all these factors together it is important to remember that high quality equipment will cost more initially but will last longer without needing maintenance or repair – giving you the best value long term.

Heating And Cooling

When it comes to aquaponics systems, there are a few considerations when it comes to heating and cooling the water. This is especially important in systems that use fish, as the water needs to stay at the right temperature for them to survive.

There are several pieces of equipment that can be used to heat and cool the water, such as water heaters, chillers, and air conditioners. In this article, we will look at the different types of heating and cooling equipment available and how they can be used in your aquaponics system:

Choose A Heating And Cooling System

When setting up an aquaponic system, one of the most important components is a heating and cooling system. Heating and cooling systems ensure that your fish and plants stay optimally healthy as temperatures can fluctuate depending on the season or your specific environment.

In order to choose the best heating and cooling solution for your aquaponics system, it is important to consider several factors such as budget, environment, size of the system, type of fish, plant species, and water volume. The most common methods include passive temperature control such as heaters and chillers, fans or air conditioning units, power outages protection heater/cooler controllers (CHCs), water-cooling towers (WCTs), thermostats, and heat pumps.

Purchasing a heating or cooling device alone often is not enough to address the need for efficient temperature control in an aquaponic system. For optimal efficiency a CHC should be used in conjunction with either a heater/chiller unit or other source of thermal energy storage such as an insulated water tank.

A WCT may also be used with an automated sprinkler system in order to evenly distribute hot/cold water throughout your grow beds. In addition to selecting the right heating/cooling device it is also important to invest in additional components including thermometers (to monitor temperatures), timers (ease programming requirements) , strain relief fitting pliers (for installation purposes).

Choosing a good heating/cooling system for your aquaponic setup is essential if you are hoping to achieve success growing your own plants and fish in the same unit. Knowing what factors you need to consider when picking out equipment combined with proper research should help you select the best system for you so that temperatures remain stable no matter what season it is or what kind of climate change might occur!

Choose A Heating And Cooling System Size

As with any other hydroponic system, heat and cooling can affect the security of your aquaponic garden. Different climate and geography will require different types of heating or cooling systems. Heating systems are the most common choice for cold climates, but temperature controllers for fans and ventilations should also be considered.

When choosing your heating and cooling system size, it is important to consider the volume of water you plan to use, as well as its temperature range. You may want to adjust the recommended size depending on your location’s seasonal climate patterns. When in doubt, it is best to err on the side of caution or stability; choose a system that is slightly larger than necessary than one that is too small for your needs.

Furthermore, consider devices like a smart controller that can help you monitor and adjust temperatures with ease throughout the year.
