Having issues with an outbreak of Cyanobacteria. I’ve tested the tank with one round of chemiclean, it’s a 100% better now. My question and what I’m looking help for is it’s on my corals, is there a dip or something I can use to kill the bacteria without harming my corals. My parameters are good other than slightly elevated nitrates and phosphates. I’m thinking about scrubbing the rocks and doing a perioxide dip before returning to the tank. Would perioxide help with the corals. What dilution should I use for the perioxide?
