Euphyllia browning out

[Everything Aquatics]

My Euphyllia are staring to turn brown the torch has always been brown though. Do they not have enough flow or light, because I can them all in lowing light and lowish flow

I, personally do not see an issue with your corals. It looks to me as though they were lacking symbionts and are gaining them back, which is a healthy response, IMHO.

Can you tell us about your water parameters and lights?

zooxanthellae. Algae that resides within the corals tissue. Gives the coral it’s color.

I have an ai prime over my 20 cube running near 95 percent(going to get another one in the future to get better spread). I have an alk of 8.8 and calcium of 430

Okay, given that and that your Euphyllia look a little bleached, I would lower your light intensity and maybe your photoperiod a little. Lack of zooxanthellae is like little to no sunscreen for humans.
