AquaFarm- The Self-cleaning Fish Tank That Grows Food

AquaFarm

The AquaFarm

Green Venture recently purchased an Aqua Farm. This is an aquarium-sized version of aquaponics. Fish are kept in large tanks and plants are kept in beds above the water with some rocks, gravel, or clay and their roots hang below into the water in the tank. The water is cycled through the system collecting waste from the fish, is then pumped into the plant beds where it is filtered naturally by the plants and it can then be returned to the fish tanks. We wanted to test out this cool new idea on a small scale. We bought ours at a local  aquarium supply store. We are currently keeping the aquafarm in the reception area at the EcoHouse. It’s doing well so far and the plants are growing pretty fast. Using the aquafarm ensures healthy plants, healthy fish and a clean tank.

How Does The AquaFarm Work?

Plants

Grow stones are placed in the planters above the tank. We transplanted a spider plant for starters, then planted lemon grass seeds and basil seeds.

The fish produce ammonia-rich waste which is pumped up to the grow bed. Beneficial bacteria convert waste into nitrates which are toxic to the fish but make great food for the plants. The plants use nitrates as nutrients they need in order to grow, while simultaneously cleaning the water for your fish.

Aquaponics was developed by the Aztecs in c.1000 A.D. They built floating islands for food plants while fish proliferate around the islands while leaving waste on the lake bottom where it was collected to fertilize the plants.  fish are kept in large tanks and plants are kept in beds above the water with some rocks, gravel, or clay and their roots hang below into the water in the tank. The water is cycled through the system collecting waste from the fish, and is then pumped into the plant beds where it is filtered naturally by the plants and it can then be returned to the fish tanks.

Bert And Ron

We called our first two fish in the aqua farm after the Veevers brothers who donated the property to the City of Hamilton in 1986.  Please welcome “Bert” and “Ron”.
