LPS Losing Color

[MHG]

My Button Polyps are losing color. The brown body is getting pale and the green color is retreating...


They were doing well in the tank for a coupld of months. I added a few more LED's across the front of the tank and this started... So I backed down the new LED's to 30% and the main LED's to 30% (RB's down to 60% from 70%).


I am not sure if this is light related...

Nitrates 0
Phosphates 0
Calc 450
Alk 9.8
Mag 1300


The brown sruface on my galaxia looks similar so I am leaning towards light but at this point I am almost off on my whites and I know people with 250 watt MH's on a 60 cube so I am not sure...


I was just about to get some more corals but I dont want to add anything when I am figuring this out...

But you know my frog spawn does not like the lower light and all my growth has stopped so I am inclined to think it is something else...

I had the same thing happen too.

I had the same thing happen too.

still the same or did they get better? I saw a thread where someone said if you increase light you need to increase feeding.
