I have a 20 gallon tank and have had Button Polyps coral for about a month. They all where open and looked healthy until a week ago. Now only half are open and the rest are closed.
My PH is 8.2
Salt level - 1.24
Ammonia - 0
Nitrite - 0
Nitrate 10
My nitrate was 20 but I have been doing water changes every 2 days for the past week and got Nitrate to 10. Could my Nitrate level be the problem? I also have a calcium test kit on the way to see if it could be that as well. Any Suggestions? Thanks
