ok i have a tri color acro now for about 2 or 3 months now and it was a very nice color and now it is like a tanish white color. my (Q) is where should it be located in the tank? i had it near the middle with strong flow. i heard that it should be as close as you can get it to the top as you can but i was afraid of it frying under my 8 bulb t-5 tek light. should i put it 4in. fromthe top of the water?

So this is a color shift to a brown tint?

IME if corals are too close to the fixture they bleach or turn white.

Too far aways and they may pale or take on a brownish coloration.

Another possibility maybe an elevated phosphate level.

As always an image of said corals really helps.

sounds like you had it in a good spot.

what are your tank parms? Make sure nothing is landing on it. with good flow that should not be an issue. How old are the bulbs. I would try it about 8 - 10" down

Check for acro eating flatworms (AEFW). The pale areas may be a collection of bite marks. Mine was doing well and all of a sudden it got pale. Look closely for the bite marks.
