Hey everyone. This is my first post. I’m working on my first reef tank ever. I have a simple 10 gallon nano reef tank. It’s been running for about 3 months. I started with live rock from my LFS. I’m doing weekly 15% water changes. 0 ammonia / 0 nitrite / 10 nitrate / 450 Ca / 0.2 phosphate. Is this regular greeen algae or the start of coralline algae? (Doesn’t really look like the coralline algae photos ive seen). Also is the purple dinos? Or the start of purple coralline algae. It’s not easily removable. I have a few small corals right now (hammers, zoanthids, mushrooms) and no fish yet. I would appreciate any and all insights/tips/help. I don’t know what I don’t know . . .
