You know I cannot for the life of my find the photos, but let me do my best to describe what I did.
Big rubbermaid tank, with a rubber box from Home Depot in the middle. The tank plumbing went into that box. The box has a series of holes cut in the side near the top for over flow and 4 circular cuts in the bottom for filter socks. I had a float switch in the box to alert me that the socks were dirty. In the big tank I had love rock and sand, all my equipment, and a couple small power heads to move water around. Then my main return was at the other end.
I had it up on a triple row of cinder blocks both to keep my pump from working too hard and make it easier on my back :) !!!
I am using the past tense here because this was a prior setup. Honestly it worked great. I even for the rubbermaid stock tank on
Amazon because I had no way to bring that thing home!
Oh and I drilled holes in the side of the stock tank, near the top, for tubing and other things, because I covered it with 1" foam board insulation to keep basement junk out and help keep heat in when it was colder out.
I will try my best to find a photo...
