Aquaponics fish tanks will be one of the first components of aquaponics systems that you are likely to consider, and in many ways we will follow similar guidelines to the ones we follow for growbed considerations. The fish tank (the aquaculture part of our system) holds the fish, a crucial part of your system and so you should choose one carefully and with an emphasis on safety, water quality, strength and long term usability.

아쿠아포닉 물고기 탱크(수조)는 당신이 고려해야 할  aquaponics 시스템의 첫 번째 구성 요소 중 하나가 될 것입니다, 그리고 여러 가지면에서 화단( growbed) 고려 사항에 따라  유사한 지침을 따르게 됩니다.
물고기 탱크는 (시스템의 양식 부분) 물고기, 시스템의 중요한 부분을 보유하고 있으며, 그래서 당신은 신중하고 안전, 수질, 강도 및 장기 사용성에 중점을두고 하나를 선택해야합니다.

If outside it will be subject to environmental conditions and so it should be able to withstand direct sunlight and temperature variations without cracking, warping or leaching chemicals into the water. Your fish tank is likely to be one of the most expensive components of your system but it is worthwhile focusing on quality and safety and purchasing a fish tank that will provide a stable, safe environment for the fish.

An Aquaponics fish tank can be of almost any shape but the most commonly used are circular. A round tank is structurally stronger than any other shape and so given that the tank may be holding upwards of 1000 litres, the round shape allows manufacturers to use less reinforcement on the tanks and therefore use less bulky materials.
 아쿠아포닉 수조는 거의 어떤 모양이 될 수 있지만 가장 일반적으로 사용되는 것이 원형입니다.
둥근 탱크, 둥근 모양  탱크에 적은 보강을 사용하기 때문에 적은 부피가 큰 재료를 사용할 수 있습니다. 다른 모양보다 구조적으로 강하고 그래서 탱크 위쪽 1,000리터의 유지 될 수 있음을 설명한다.

 A rounded shape also allows for much easier water circulation and flow in the fish tanks, and this has several distinct benefits for water quality and fish health:

둥근 형상도 어항에서 훨씬 더 쉽게 물 순환 흐름을 허용하고,이 수질 어류 상태에 대한 몇 가지 뚜렷한 장점이있다

  •  Still water will naturally 'layer' or stratify into different temperature bands and so good water circulation prevents this type of thermal layering and thus helps to improve water quality.
 정지된 물은 자연스럽게 '층'또는 다른 온도 대역들로 층화되고 좋지않은 물을 순환시켜  열 레이어링 유형을 방지함으로써 수질을 개선하는 데 도움이 된다.

•  A good flow of water provides the fish with a current to swim against, which increases their health   and the quality of their flesh if the fish are for consumption.
 좋은 물흐름은 물고기를 소비하는 경우 물고기의 건강과 고기의 품질을 향상시켜 품질 높은 물고기를 제공합니다.

•  The fish also seem to naturally enjoy playing in currents or waterfalls of water.
 물고기는 자연적인 물흐름 또는 떨어지는 물을 즐기는 것으로 보인다.
•  Good water movement also prevents a layer of protein forming on the surface of the water, which could inhibit the exchange of gases between the air and the water.
 좋은 물 흐름은 공기와 물 사이의 가스 교환을 억제 하는 물 표면 상에 형성되는 단백질 층을 방지한다.
•  Good water movement increases the surface area of the tank. With the surface water constantly changing you dramatically increase the rate of oxygen exchange.
 좋은 물 흐름은 탱크의 표면적을 증가시킨다.  물의 표면으로 지속적으로  산소 교환 속도를 증가 변경 시키는 극적인 역활을 한다..
•  Increased oxygen benefits not only your fish, but also the de-nitrifying bacteria in your system, as well as inhibiting harmful bacteria that thrive in an anaerobic environment.
 
산소는 물고기에게 이로울뿐만 아니라, 시스템의 탈질산화 박테리아뿐만 아니라 혐기성 환경에서 번성하는 유해균을 억제한다.

•  In a rounded tank, solid waste will often gravitate toward the bottom centre of the tank - strategic placement of your pump will pick up almost all of the solid waste quickly.
 둥근 수조에서는  고체 폐기물이 종종 탱크의 바닥 중앙으로 몰려, 이러한 고체 폐기물을 펌프로 걸러낼수 있는 전략적 장소를 형성케한다.

Square or rectangular fish tanks are also very common and can be useful if you are working in a confined space, be it indoors or outside.
 정사각형 또는 직사각형의 물고기 탱크도 매우 일반적이며 당신은 밀폐 된 공간에서 작업하는 경우 실내 또는 외부를 유용하게 사용  할 수 있습니다.
Square or rectangular fish tanks can be commonly found in aquarium outlets and can be hand-built if necessary. 
 정사각형 또는 직사각형의 물고기 탱크는 일반적으로 수족관 매장에서 찾을 수 있습니다 손으로 직접 만들러 사용 할 수 있습니다.

Care should be taken to ensure adequate water flow, and ideally if these tanks have rounded corners it will assist in the water movement. IBC (International Bulk Carrier) totes, or high quality, food grade bulk shipping containers such as Macrobins are commonly used square aquaponics fish tanks.

Fish Tank Materials

Fish tanks are most commonly made from a food-grade plastic material, regardless of their size and shape. Such tanks are generally the most cost effective and are readily available across the world, from a wide variety of sources like Homestores, DIY stores, Aquaculture outlets and so forth. If you are re-purposing a tank that has an alternative main function, care should be taken to ensure that it is made from a material that will not compromise water quality and is safe to be used for fish, and in a system, which will provide food for human consumption.

In all cases the fish tank should be made of an opaque material that is UV resistant and which blocks sunlight as direct sunlight will encourage algae growth which is generally detrimental to your system (primarily because algae is a prolific grower that also need oxygen to multiply and so depletes your system of the available oxygen needed by your fish, bacteria, and plants) Smaller systems can use standard glass aquariums, but again, care should be taken not to keep the tank in direct sunlight.

Backyard aquaponics enthusiasts may choose to make a fish tank either from concrete, or out of a wooden structure then covered with a food-grade liner. Concrete needs to be handled carefully as it can seriously affect your water composition causing imbalances in your pH. If concrete is used it should be sealed with a food safe commercially available sealant. Wooden tanks (or any other type of material for that matter) can also be built and then lined with a commercially available liner to make it waterproof. With these fish tanks you need to be careful that the tank will be structurally strong enough to withstand the pressures and stresses of the water that they will be holding.

Ponds can also be used in an aquaponics set-up, although care should be taken as an outside pond may contain and spread undesirable bacteria or insects through your system and again, compromise the water quality of your system. Some permaculture experts have also successfully converted swimming pools to self-sustaining aquaponics systems - the excellent work of Geoff Lawson is well worth looking at in this respect.

Fish Tank Size

Aquaponics is an integrated symbiosis of fish, bacteria and plants, and so when considering fish tank size you have to take into consideration the size of your entire system. Your growbed (or growbeds) need to be able to perform various levels of filtration on the water and waste coming fro the fish tank, and so it would be no good having an enormous fish tank with lots of fish, if you are using a tiny growbed. As with most things in aquaponics we are striving to design and build a balanced system.

As a general rule of thumb your growbed volume (in a media based growbed system) and your fish tank volume should be at least equal, with preference being for a slightly larger growbed volume. This simple rule will usually ensure that you have sufficient biological filtration, mechanical filtration and mineralisation capacity for your fish tank.

Conclusion

In summary, your fish tank choice will be influenced by space, environmental and size considerations. There are a huge variety of choices and it can be bewildering at first, but if you focus on safety and water quality then you cannot go far wrong. Providing your fish with a tank that meets their needs will ensure healthy and happy fish who will power your aquaponics system for years to come. Ensure the size of the fish tank is suitable for the size of your growbed space and your fish, bacteria, plants... and you, will be able to live harmoniously together.
