LFS, I've got a CA reactor so only needed a little bit for things like this.

If your planning on supplementing littlesilvermax seems the guy for buying bulk.

I was really hoping that someone would tell me that those were not aiptasia and that I should leave them alone. The dark brown one on the right and the almost purple one near the center look quite nice. I really hate to nuke them . What is the other purple growth near the center? I assume that it is some kind of coral since the broken tips are pure white. What type of macroalgae is growing on the left? I'm assuming that it is a keeper. Am I correct?
