How are things looking todayI can't figure out why my gonis are not doing well. Everything else is thriving.
Chemistry is spot on...
Salinity - 35ppm
Temp - 79° F
Alk - 8.4dKh
Cal - 440ppm
Mag - 1400ppm
Nitrates - 20ppm (a little high, but doubt it's the cause)
Phos - 0.08ppm
All softies, including hammers, frogspawn, zoas (which are exploding in growth) and all fish and inverts are doing great. The only corals closing up and struggling right now are the gonioporas. It's been a few weeks of decline. Two already bleached out and the remaining two are extending less and less each day and now barely extend at all. They were vibrant and doing well until recently. I would add that I have recently gone through a Dino outbreak, which has now been fully cleared up for about a month. Two 25% water changes have been done since. There are no visible issues at this time. All looks good.
Any idea what might be causing them to struggle?
