SSIA...I have been battling a cyano issue for the past month and I have tried all of the suggested 'natural' methods without success, this stuff is relentless and comes back almost instantly. I see that Chemi-Clean has been used countless times successfully in reef tanks but I haven't specifically read anyone using it that has an anemone in the tank. I have a GBTA and want to make sure it's safe for this guy. Thanks.
