will dimming mess up corals?

[terminallance]

Will dimming my leds mess up my sps and lps? I had my leds on about 75-80% and think it is too bright alot of sps are browning and my chalice looks as if it was starting to bleach so today i turned it down to about 35%~ is that too much am I going to mess with the corals too much? Or will it be ok to leave it there for a few weeks and slowly increase it?

Browning is generally from either too much phosphates or too little light. I would drop it to 50% or somewhere around there and go up or down from there. Remember it can take a couple weeks to really see a difference in coloration. Check your params first though, bleaching can also be caused by low alk.
