So you pump the water into the top of the plant tanks and it constantly returns to the Tilapia tank through the bottom pipe?
How many Tilapia can you grow in that tote?
Do you have sand or soil in the bottom of the tanks or is it just rocks?
Thanks for the info.
I'm hoping to keep about 30-40 Tilapia total.
There isn't any soil, only inert rocks. I've filled the containers 1/2 full with lava rock (very sharp/porous for bacteria to live in), and top layer of river rocks (smooth, won't cut your fingers or plant roots).
Water is ONLY pumped from the sump, into the fish tank. Look at the last picture, the pipe on the right bends from the in-ground sump, upwards into the fish tank. Look at the left side, there is an overflow with bulkhead drilled into the tank. The water travels down through this pipe as it's being displaced, and it comes up and into the growbeds through pipes that are SHORTER than the height of the fish tank bulkhead.
Confusing, right? It's not easy to explain, but it's a very simple process. I hope this helps?
Nice setup, I've been dying to get one of these setup for years now, but not enough land. Looking to purchase a new place now and space for a greenhouse and aquaponics setup is high up on the priority list. When I get situated I may be PMing you for advise, if you don't mind of course.
Sweet, you'll love aquaponics, it's much easier than planted tanks (and you can eat the rewards). Sure, hit me up if you need some pointers.
