Montipora SPS 20K MH?

[xxnonamexx]

I have 20K MH and a 55gal tank, I have assorted corals but starting to get into SPS since they thrive in light and I have the 20K MH for them. I notice one Montipora not doing so well. All water parameters are fine. Any ideas? Thanks

your post seems very general, what are the water parameters even though they are fine...? and tank specs?

 

[Deanos]

What are your alkalinity and calcium levels?

 

[nanoreefer22]

Dont forget those magnesium levels.

Also wattage and number of lights.

not doing so well can have many meanings.
