Help! My corals

sterling

Member
Some of my corals don't look good.
My hairy mushrooms, which I've had for well over a year are shriveling up and two pectinia don't look good. They were doing very well.
My other corals, wellsp., gorgorians, torch, cup, frogspawn, leather, polyps, colt, some new sps I got etc look good.
My water parameters are as follows (I tested last night):
ph 8.2
alk 2.8 ml
cal 410
nitrate 0
nitrite 0
ammonia 0
salinity 1.025
temp 79.0
The one thing I don't have a test kit for is iodine, but I dose weekly for that and stronium, molb. and magnesium.
Any help, thoughts out there.
