Our's is just a holding space for our skimmer ect... We have had a smaller tub inside with holes for flow cut in it and then some rock and egg crate for things like the blue matting stuff and algea pads of charcoal. We even tried to grow some calurpea but that didn't go well.. Right now ours is just a tub.. lol
If you figure out how to make an actual sump with baffles ect that would be interesting..
somewhere I have a picture of the monster behind the tank.. lol I'll have to look!
Hi my name is sarah, and I've got the Upgrade Bug! Do not meddle in the affairs of Dragons for you are crunchy and good with ketchup!!!!
Jason, what kind of tubs are you using and how long have they been up and running. Ramoth mentioned she has had problems with leaks developing over time, which is something I would really like to avoid.
