Hey, all. I thought I had skipped the uglies by having a long, lights-out cycle, and using maricultured live rock to add diversity to my dry rock structure. I am seeing coralline growth, but unfortunately, it also looks like I’m starting the cyano phase anyway. I have a lot of green cyano, and am now starting to see small spots red cyano. It’s only on the dry rock, of course. Should I just leave my lights going and continue business as usual or is it worth trying a few days of blackout? I don’t want to overreact and start dumping chemiclean into the tank. I’ve seen conflicting info about adding more NO3/PO4 to combat cyano, as opposed to cyano being caused *by* the nutrients. I don’t want to zero out and risk dinos taking over.
