Yeah, basically impossible to pinpoint.I know there's a thousand questions. It only takes one thing to cause issues. Hows the water flow?
Also, less light would cause more issues. They can do well above 75 par.
But I assume my par is higher now but ill see if can get my hands on a meter and the flow is not much.
I have alot of Euphyllia and they dont like flow, so I keep it pretty low. There is enough to keep detritus off and sometimes I crank it up to 100% for 10 minutes for detritus removal and nutrient export, Probably once a day.
