Hoping someone can share some guidance here. Today I came home and noticed a pretty good size red montipora colony had turned mostly white though the polyps are all still showing bright orange. I’ve had this Monti for about 2 years now, and it’s never shown any similar issues. Looking around the tank, other montis of the same kind, and other kinds of montis are also faded in color though not as significant. I have also noticed that my birds nest and pocilipora polyps are not extended, and my bounce mushroom has been looking deflated. Other than that, my acros are currently looking good which is a bit surprising as usually I’d expect any problems and they’d be the first to go.
checking water parameters, nothing seems too out of the ordinary.
salinity is good,ph is stable within my regular daily fluctuations.
alkalinity, calcium, mag are all stable and monitored with the trident.
I did notice a small nitrate and phosphate spike. This occurred Over a 4 day period, and nitrate went from 2ppm to 5, and phosphate from .02ppm to .08ppm. I did have a cyano outbreak, resulting in me dosing a liquid cyano remover 7 days ago. Tracing this back further, in the last month I believe the cyano took over once I finally beat out a prior hair algae problem.
I typically do water changes every 2-3 weeks. My only suspicion right now is that I recently removed my carbon and turned off my UV when I dosed to kill off the cyano. I did put new carbon in tonight and turned my UV , and I am making new saltwater for a water change.
Any other thoughts on why this might be happening or something I might want to check on?
