Is it that green still to this day?
It could be the beginning of corraline algae. If it doesn’t blow of or brush of it probably is.I’ve had a tank running 7 mounts and I changed my lights to new stronger ones and my rock is turning green please help
does the coralline automatically appear or do you have to scrap some coralline from a live rock?They turn more green, maybe get a diatom outbreak, some hair algae...this is all normal part of the tank maturing, eventually coralline will take over and you'll have purple, pink, green coralline covered rock.
