I'm having an issue with some of my corals in my tank but not all of them.

Softies - All are good
LPS - Frogspawn, hammer, chalice, torch, favia, trachophyllia, blastos are all doing good.
SPS - One stag and one Acro doign awesome, one mille ...ok, other acros doign terrible and montis only last several weeks.

This is on a 190 gallon tank with a closed loop.

Lighting is 4 AI SOL Blue's but was only recently hanged over, prior to that I was running two 250W metal halides and had the same issues.

Parameters are as follows:

Calcium 400 (a little low but not terrible)
Alk 8.8 (would like it high but again, not terible)
Magnesium 1400
PH 7.9-8.0
Phosphates .5 (not so sure I trust the test on this because it's tested high on every tank I've checked)
Nitates 20
salinity 1.026

temp 79.5
