phos,na,ni. all zero, can to much light do it. i have my tank in front of a window and sometimes open the curtins all day

Letting in natural sunlight can affect acros and also increase algae blooms.

 

[organism]

too much or too little light would defintely do it, although water params can be a major issue as well as the water movement around the coral

Getting a good skimmer would also aid in getting your acro colors back.
When a new coral is introduced to a tank it must be accemated correctly and placed in the lowest part of the tank.

I've never seen too much light brown out a coral. Bleach, yes, brown, no.

I have seen too much light from low K bulbs change colorful corals brown.

I agree but IMO there is 2 different kind of browns.
Turd brown is from too high a nutrient level but sometimes I have corals get a tan/brown color. Specifically on my bonsai, efflo, and nana. The light tan/brown color seems to be from stress and its a PITA to get rid of.
I hope that I'm making sense

Agreed
