LPS question

[mrtian97]

my water param: Ca 420; Alk 8.4; pH 8.3; Mg 1,200, Nitrate and Phosphate is low.

I have several LPS, and Monti cap. My torch coral and Alveopora do not look happy, the other corals like duncan, zoa, acan, favia and the monti look fine. Moderate flow with medium light with radion G3.
Any suggestions?

When you say nitrate and phospahate are low, that means what? Numbers are far better then just saying they are low.

How long is your tank running??

I see some O2 bubbles on your rock, can you bring out a macro pic of that?

What is your life stock list?
Yellow tang isn't looking on it's best either.

Has your salinity been stable? I would keep a eye on that too.
