Coral Health Question

[Saltguy768]

Hi Everyone,

I am just getting back into corals. I woke up this morning and found my corals not open and not looking that great. I checked my water and got the following values below. Let me know if anyone has any recomendations.

Calcium: 400
Carbonate: 12
Phosphate .5
Nitrate 5

What’s your temp make sure there’s no fluctuations in that also did you just dose something in the tank? Did you change lighting recently what’s your salt level I would try adding any carbon you might have in there to soak up any toxins that might be in the water check for ammonia and nitrites as well!!!
