montipora bleached ?

[plexx]

So after finally getting my tank to where I want it my monti. on the back wall looks bleached. I have T5's on the tank and my parameters are
alk 8.6
sal. 1.026
phos 0.05
nitrates 0.10
cal 450
mag 1425
Everthing else in the tank seems good, maybe the monti is to high up in the tank , not sure.

I went from kessil led to t5 4 bulb , maybe the extra light did it. The rest of the tank is good so don't want to mess around with the light to much.

Bleaching usually a sign of too much light too soon.

+1 for too much light too soon. Whenever a new light is installed, it is always best practice to ramp it up slowly to acclimate. In your case, you can consider raising the light further from water, and slowly lowering it by 1/2" a week to where you want it.
