Here is a shot of the Grow Beds from the far end from the tank. The beds closest to you need to be cleaned. They are full of sand. Forgot something in the rush to get this thing setup. I got some of the PVC fittings installed and used the small filter to pump water into 4 of the barrels on the south side. they fill and drain just fine. Hope they don't overflow too bad till I get all the tanks flowing. I really don't like the Plumbers tape holding up the drain gutter. Probly will do something I like better. Gotta get some more gutter also.
