I have a ton of different montis and just recently the polyps are not expanding alit they have for years.

I have a few large sunset montis and the green polyps usto be huge and blow in the current now they lok all sucked in and only slightly more expanded at night. Flow has not changed, lighting is the same. no new fish bitting.

levels were good will re check tonight.

but is there one thing that could be the main issue?

Mg?
 
havent checked those in a while as tank is established but i think i had a spike in phosphates will have to check
