I have a great deal of green algae growing in my 120 gallon reef tank. I do use RODI water. I put in some Weiss Algae Magic about 2 weeks ago. I continue to have a significant amount of ongoing growth. Attempting to remove the algae from the live rock is difficult. It appears to cling to the rock very well. Does anyone have suggestions short of removing the Live Rock and scrubbing it off?
