I found some bubble algae on a zoa frag rock. I have been keeping it off other rocks, not be cause of the algae but the Zoa’s seemed to like lower light and open better. I saw it when I was moving things around. The bubble are still very small. Going to take the rock out and try and chisel off part of the rock with the algae on it there are no Zoa’s in that are anyway. It after I remove the algae in there anything that I need to do to make sure that the bubble algae is gone? Was thinking a squirt of H2O2 over that area. Yes I will be working on it out side the tank. Will get some pictures this afternoon when I get home from work and while I complete the process.
