Pink/red sps turning green

[Duncmac]

I have a rose milli and a tricolor valida that are exhibiting strange coloration. The rose millepora has begun to turn green on its skin. Polyp coloration is unchanged.

It shows stronger than on the valida, which now has a teal base and pink tips vs the purple color it had when I got it. It's near completely encrusted its plug during color change-which makes me feel even weirder about the whole situation.

The only change was moving the frags to sandbed when they bleached during LED acclimation.

My other sps are growing and colored fine including monti cap, setosa,monti stellata, bali slimer, blue tort...

Need an alk kit and more reagent for my hanna checker.

Nitrate- 0 (API kit handicap-is there such a thing?)
Ph- 8.1
Salinity- 1.026
Temp- 78

Params have been stable as above. I'm aware no phos or alk is a bummer.

I run an evergrow d2120 over a sumped 20gal long. Sca 301.skimmer, GFO and carbon.

Leds 18"from surface at 60%blues 25% whites

I am having similar issues with the same 2 corals under LED. I suspect high nitrates but my salifert nitrate kit is on backorder. The API one is not good as it always shows low or 0. I also have the same corals under MH/LED with better color but that tank is less fish loaded and double the water volume.

You should list more parameters. ALK CA MG, and P04

They are not getting enough light more then likely, and personal experience first hand pinks are tricky under leds.

I don't have test kits for cal or mag and am waiting on refills for my hanna checker. I'll check and post asap.

It's really strange. PE is still good and growth doesn't seem to have halted.

Let me know if you find reason for coloration.

I have a 20g long. It's only 12" deep. I had it about 4"from the surface and it bleached. Maybe after a longer time it may fare with light better? Shock from the t5 to led transition shouldn't be an issue now.

I tried more lights also and it just caused stn on the valida. I reduced the light to what I had before and am waiting for it to acclimate. The stn stopped. Give it time and stable parameters.

I want to rephrase what I said above, I think a lot of led are missing the proper spectrum for a lot of pink/orange/red corals which can make it harder to achieve .I tried leds for months with no avail. I would stick with it and give them a few months to get adjusted. I would try to get you nitrates a up around 1 to 2. I am not sure if that will mend the issue. I got a ultra blue milli that I put to low that complete turned completely green as well as the coralites smoothed out. I eventually moved it 4 inches under 250w halide it came back from the grave.
