What are these called

There seems to be a lot of people here in Killeen that like it........

Get a handle on it now. Some of the majanos are really cool looking and if it were a fowlr tank I'd say don't worry. In a reef they will spread fast, not like aiptasia but they are much harder to get rid of in my experience.

Be careful using a calcium or kalk mixture because, depending on tank size, it could mess with your parameters. The Blue Life Aiptasia Control is really awesome stuff and you can use a fair amount of it even in smaller tanks.

I wouldnt wase money on 'over the counter' Aiptasia products when you probably already have something that will work just as well on hand. Ive found that liquid calcium works as good or better than anything else and the excess will most likely be absorbed by the system, just dont over do it.

I pulled the rocks out and used viniger on them, worked great. Now I need to fill the bear spot in my tank. They were growing like weeds. Again thanks for all the replies.
