My Tyree Pink Lemonaid - Bleeching from the back. Quick Q - Lights?

[Grandlotus]

Hello.

I have a 65 Gallon with 2x MP40's (75% blue mode) and 2x Radion (60% at max).

Nitrates - 0-10ppm
PO4 - 0 Detectable
Calcium 380-400
Alkalinity 8dKH
Magnesium 1300ish

All of my other corals are doing good and nothing has changed in my tank.
Got the Tyree Pink Lemonade as a frag and it encrusted the rock.
It is higher in the tank - but not above other corals that are doing well. Flow is also high.

Is it possible that this is too much light for this coral?
Should I move the coral down lower or adjust the lights down to 55%?

The coral still has coral on the side not facing the lights and the side facing the lights there is still color but it is washing out.

Ideas?
Thanks.

How high off the water are your Radions hanging?

 

[Grandlotus]

Radions are about 8-10 inches above the water level; followed the factory recommendations.

I would move the lights higher, 12 to 13 inches. I had to move my Maxspect Razor (not as good of a light) higher after bleaching some of my sps. You should also be feeding the corals in an LED lit tank, based on what I've been reading. I try and feed a pinch of Reef Roids every day.

I'm not sure about the light as the main issue. I had my pink lemonade under radions and it did mostly nothing. It's mounted just over halfway up on my overflow. Now I'm blasting it with radiums and t5s and it's coloring is better and growth is much better.
I'd frag part of it and move it lower and work back up. Maybe it's getting to much of one wavelength.

I feed coral frenzy 1-2 times a week.

I will move my lights up higher to deal with the two issues mentioned:
Two much of on wavelength of light and
Possible bleaching due to excessive light.

I will update when the coral revitalizes or seems to get worse.

My PL always liked high flow and light... it could be a combo though of too little nutrient and then the high lighting, mine always a bit temperamental and it bleached on me at least once from too little food. Trying upping the feeding a bit and for the time being, probably won't hurt to reduce your photoperiod for a bit before upping it again slowly.

Thanks.
I raised my lights to about 11 inches above and will go to 3x feedings and see what the coral looks like in a week.
