I have a button polyp that has been heretofore happy. The last several days all of the polyps will not open. There is nothing on it that I can see.
Tank parameters are:
Temp 78
Ammonia <.25
pH 7.8
Nitrite 0
Nitrate 10
KH 11
PO4 .25
SG 1.024
I use a Red Sea refractometer. I also have the lfs check my salinity and they use an electronic device to verify SG. pH has been 8.3 until I started using Red Sea Pro salt to mix the water. I do a 10% water change weekly. I was purchasing my water from lfs. They use instant ocean. I still get my RO/DI water from lfs as I only use 1.5 gal weekly.
