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 !
