help!!!!!!!!!!!!!!! i have brown rust colored algea stuff growing on my sand i thought when i took out my bubble coral that was dying it would clear up and I have a sand sifter that is very shy and obviously not doing it's job so i don't know what to do. help don't even know where to start i have done water chages, the water tests fine and the fish and other corals are happy but this rust algea stuff is reallu annoying, no fuzzy growth its just turnoing the sdand to a very un sightly rust color.
