I just got over a pretty bad red algee takeover. Reduced the lights to 6 hours a day, sucked what i could while doing water changes, and now its nearly all gone with only a few small patches left that i'll hopefully get this water change. I'd also moved my powerheads around a lot to try and get more flow in those area's. The algee was actually a pretty good indicator of area's that had low flow. Theres apperently many different causes, too much light, phosphates, dirty water, etc. But mine seemed to be a flow issue after i'd moved some rock around. I didn't use Coral Snow, but.. if i had SPS or coral that was more dependant on light i probably would have.
What my LFS told me that actually made a lot of sense was that even using Coral Snow or any other remover, if you dont' get rid of the original problem, it'll just come back.
