Killing Pest Coral

[martinmcnally]

Anyone have any experience with trying to rid your tanks of GSP or some other pest corals?

I have 2 problems. Green Star Polips. I thought I had it all under control I removed the rock, scraped off as much GSP as I could then poured boiling water over any tissue that was left to get it off. The rocks looked completely clean when they went back in and now its coming back

I also have an invasive zoa.

This one is killing other coral all over the place. I have resorted to scraping it off rocks and popping their polips
