Stylophora help

[Radicalrob1982]

Hi. Thanks for reading and any help

I have a green stylo that's not doing so well. My parameters seem to be in check. I recently switched to a vipar spectra black box mounted about 12 inches above my 20 long tank. I have blues set at 80 and whites set at 1. But this coral has been slowly turning brown and white. Is this too much light ? I have noticed that it's slowly getting very small new polyps every day since it went this way over the last month. Do these corals recover? My alk I've been testing daily and I keep it steady at about 7.5 to 8. I keep it this low because I run a pretty clean tank with low nitrate and phosphate.

This is what it used to look like. Not sure as to what is happening. I have two Digitata and a rbta and they all seem fine. As well as my hammers and zoas. All other corals are doing great. I keep medium flow in my tank with a sine wave pump. Should I try lowering the coral to the sandbed?

Any help or advice on keeping stylos would be appreciated

Thanks !

Bleaching would usually indicate too much light or too much heat. Do you have access to a par meter? Do you track tank temperature?

Stylos, along with birdsnest, are one of the corals I just can't keep. My acros do really well and base out/grow, but any birdsnest/stylo I try to keep slowly dies over a few months.

Do you have other corals/SPS that are doing well?

I don't have a par meter. My temp stays between 77 to 78 degrees Fahrenheit. I have an rbta and two monti Digitata on top of my scape and they're doing well with good growth. Stylo is just a bit lower than that

Ya I have two monti Digitata and they're doing good. Good color as well and some growth. I have then in medium flow and they seem to be happy

This isn't all my coral but as you can see my corals are doing pretty good and healthy looking

I'm going to keep it on the sandbed for the next month to see how it responds. Hopefully it bounces back. It's a beautiful coral
