Powerhead getting clogged!!
My powerhead was putting out water at a very low rate. I moved the bottom around, with out anything on the end, and a lot of gunk came out of it. I had some sponge pad on the end held with a rubber ring. Then put a replacement sponge over it. Thus guess putting a long tube on the end with floss in it will help.
Anybody else have this problem? If so what did you do?
