Hey guys I need some help I tested my alkalinity last week and it was 11 now it’s 11.58 I haven’t done anything but a water change I thought the corals are supposed to use the alkalinity why is it going up?(how do I make it go down) I haven’t used aptasia x or anything else in the tank besides regular feeding of my fish and I fed my corals once with reef roids.
these are the parameters I can check, I’m waiting on a calcium test kit to arrive.
corals I have are
-4 different gsp ( white stuff on it doesn’t seem like a sponge not sure if coral death)
-3 different zoas (not doing the best)
- 1 birds nest (looks the same as it did at the store)
-1 goniporia (has opened and seems okay)
- 1 candy cane (hasn’t puffed up)
-1 Kenyan tree
