I have a 1yr old Reefer 350 bought new and purchased what I was told was purple live rock. I did have a biocube 32 that I transferred everything from to this setup which also had some of
the same rock that was 6 months old. Some of the rock in the lower par areas, especially in the front lower of the tank looks to be whiting out. Assuming all parameters are stable, would this be new coralline algae growth because If you zoom in you can see this pinkish purple color growing over the rock. Just making sure I don’t have another issue. Thanks
