As i have been struggling with the annoying green algae its just freaking annoying. :banghead: As i look at other members and what they are selling i see they have the same problem. How can we control this problem besides buying a yellow tang or any other fish or invert? Does anyone have a suggestion? I know someone said to freeze it over night but that is impossible if you already have corals growing on the rock etc. Any suggestions:scratchch ?
