So in between last weekend and this weekend my tank has done a 180 on me. The coral in the tank look and are for sure having problems. It seems to be centered on monti and hammer coral right now and a couple other small polyp coral but not every one. I've tested the water and all the levels are good and nothing is out of range or anything. I could do a water change but if the levels are fine I'm not sure what good hat will do honestly. At this point I'm not sure what to do or if it's just a freak thing going on in my tank that I can't help. Something's are healthy and some are on the brink of death.
