What are your params?

What are your params?

I think @Daniel@R2R should make a template or rule for people who ask this kind of questions so that they always put parameters before posting the question.

I for one always put on all my parameters when asking about coral or fish behaviour to avoid people to response with “what’s your parameters“ as in reality it is hard to know what’s wrong without knowing this basic important information.

Agreed. Always the first place to start.

I’m sorry!
All parameters are under normal!
Ca 420
Mg 1300
Kh 8.5
No3 2
Po4. Undetectable

undetectable PO4 is not good. how are you measuring PO4?
Are you using GFO? Running a refuigum?
it could be starving. You'll hear many different values but I think most will agree that an absolute minimum of .03ppm PO4 is necessary.

Yeah, nitrate and phosphate are to low.

Yeah, nitrate and phosphate are to low.

Simple solution to this is to feed your fish/corals more. See if that improves the coral.
