Hey everyone I am needing some help with my chalice coral. I just got back from college yesterday, and noticed my chalice had white spots on it which I’m assuming is where the skeleton of the coral is showing through. Anyway, i got home later yesterday so I tested my numbers today.
Salinity 1.026
Temp 80 F
Alkalinity 7.4 dKH
and calcium level at 220ppm....
I have no idea how it got that low. I’ve been having my brother dose the same amount every day for the last two years and it’s always been fine. Assuming it is that low I guess I need to bring it back up slowly. However could my calcium test kit be too old? It’s 2 years old. Also in the pictures my torch coral is really close to the chalice, but I don’t think that would be the issue. They’ve been like that for 6 months and the chalice jut stopped growing towards the torch. Any help would be appreciated. I dont have a nitrate and phosphate test kit, but I can get the numbers later tonight. Tank is 93 gallons and 4 years old. 6 small fish. Thanks all!
