What is your phosphate level?
How long have you had the LEDs? Are they adjustable?

 

[ron168]

Are these new lights or did you change/replace the bulbs? What lights did you have before? How high are they from the tank? Maybe the new light/bulbs are too much for them because of the change.

My phosphate is 0 am running phosphate sponge and rowa phos and the only resone why I changed them was due to the browning and no the leds are not adjustable

Could it be that light are left on to long they go on are 12pm and are off at 10pm

I believe most people run a 10-12 hour light cycle for actinics, however the day lights will be much less. So if your running full on for that long that could be too much.

Could it be due to low o2 levels

If your phosphates are 0 and nitrates are only 5, are you feeding heavily? You should be at least feeding a good amount imo. Possibly mixing in coral food?
Any time your running a low nutrient system, you still have to make sure your corals are getting well fed. So if there's very little nutrients in the water for them, then you have to make up for it somehow. this is just my opinion and others may feel differently.

I believe brown but healthy sps is due to high levels of nutrients, are you running a skimmer? Another way I unofficially gauge nutrients is how often I'm cleaning the glass. I try to get it to two or three times a week
