is this corraline algae?, ive noticed its been growing ever since i started dosing calcium a few weeks ago after i tested my calcium and it was below 300. i got it upto 380 and ive noticed this growing, tank is going on 5 months old no other algae i can see, though the purple corraline is spreading to my other lr and its also growing green in some spots its not cyano because when it grows on the rocks it doesnt rub off pretty hard
