Here is a picture of my aquaponics project in the backyard. The blue tank is my 210 gallon fish tank from Aquatic Eco-Systems. The grow beds are 100 gallon stock tanks purchased at Tractor Supply.
You may notice that my grow beds will not completely drain out all the water. Since I live in a sub-division with neighbors very close-by and I have an irrigation system, I decided not to dig out the 10 inches or so that would be required for the grow beds to drain fully. As it stands, 10 inches remains in the bed and 15 inches drains back into the fish tank.
I plumbed the PVC through the side of the fish tank so I can attach a lid for shade and to keep out the occasional red shoulder hawk and osprey that might find it easy to feast on my fish.
I'll post more pictures soon as things progress farther.
