So I put bunch of macro's in what I've designated as my fuge section of my sump and I've run into a few issues. First off, I only have a handful of small rocks in there and immediately I noticed that the chaeto was getting caught on it, so I put a piece of plexi in there to separate the rock area from the chaeto area and now the chaeto tumbles nicely from the over flow pipe. Now the problem is I had no noticeable flow in the other part of the fuge for the other macro's so I put a small power head in there...its working fine except all the macro's are stuck to it. Will the macro's grow fine stuck to the power head? Any other suggestions?
