and put a power head in the fuge section. I would come home, use a tooth brush to clean my rock and net out all the gunk that floated to the surface. Tank would look better. I go to bed and then to work come home and do it all over again. Now I have bare rock in places again. It was also all over the substrate. Once I get it all gone I can add some corals and see how my 4 bulb light grows them.
