All my rocks have about 1/3 to 1/2 covered in coralline and seems to be rapidly spreading, although there's still some brown and green algae mixed in. What's odd to me is that there is not a speck of coralline algae on the glass or plastic parts. I thought coralline grows on powerhead and glass first. Can someone confirm if this is actually coralline? Also, there seems to be some batches of deep red growth (seen in 2nd pic). Is this a Cyanobacteria, sponges, or a different strain of coralline?
Picture was taken under natural white light leakage from my house and windows, tank light was off. Rocks are live ocean rock, it started with lots surface life and debris, but it was nearly bare of coralline algae (seen HERE).
