So my dad and I have a 90 gal reef that has been overrun with cyano for sometime but we are just now getting serious about getting rid of it. My dad thinks it would be easier just to drain everything and start from scratch but I disagree. I made a bet with him today to give me 3 weeks to try to get rid of it myself and if that doesnt show any signs of promise we are going to reset the tank. Currently in the tank are 2 percula clowns, 3 peppermint shrimp, ~10 astrea snails, and a small frag of galaxia coral with about ~50 lbs of live rock. Any suggestions on how to get this under control so that we dont have to reset the whole tank? I just cleaned the protein skimmer out this morning. Any help would be greatly appreciated!
