I have been accumulating alot of small frags from friends and LFS ($5 shelf).

I am having much success with most SPS added to the tank with the exception of purples and reds. My reds have good plyp extension but are slowly bleaching, the same with my purples.

I know this is overly vague but are the generic rules for coral placement in regards to coral color?

I ran a search and didnt find much to answer this question.

Water parameters are stable and within range. I can not test phosphates at this time. Is phosphates a contributing factor to bleaching? ( I have been/am running a small amount of GFO just to be on the safe side)

My lighting is 36 3w LED across the middle of the tank 22 RB run at about 50% the rest are a collection of whites from warm to cool run at about 50%. The LED's are supplemented with ATI 48" T5. 2 blue, one coral plus, one purple pluss. The coral plus/purple plus are only on 4 hrs a day, the blues are on 8. THe LED are on for 12.

any help appreciated!!
 
If your corals are bleaching, not to be confused with tissue necrosis, your should move them down in the tank. Bleaching=too much light assuming all other parameters are good. Purple acros are usually high light in general.
 
yes. nutrients can be a big factor with corals bleaching under high light. No, there are no general rules for coral placement in regards to color. as long as it is between 100-300 par you can get any color.
I know nothing about leds but if your water chemistry is good with little nutrients, majority of acros can be acclimated to stronger lighting. (I use halides and t5's)
test your phosphates and nitrates pls.
