so now that I've seen your old setup mainedukblaster, I would like to ask you for your advice... My idea was to set up the 55 gallon drum standing up for the smelts, so they can swim around not bumping into the walls... but looking at your setup i obviously noticed there is more ground area when the tank is laying down. now to everyone, here's what I'm gonna set up tomorrow. please feel free to give criticism on my idea so i don't learn the hard way. 55 gallon drum, 1000 g.p.h. pool pump without the filter in it sucking out of the drum, into a 5 gallon bucked acting as my filter, a layer of cotton then a layer of activated charcoal with a layer of cotton on top. out of the top of the 5 gallon bucket a hose going into the top of the 55 gallon drum for the water return. what do you guys think??
i glued a PVC cap on the end of my intake (right where it comes out, ) and drilled a bunch of holes in it.. worked great, you could use steel/ copper wool. stuffed in a intake pipe too.
Do not use steel or copper, it will rust. Rust will kill the fish.
