GOOD OR BAD? HOW DO i GET RID OF THEM?

[RWL]

I had many of those anemones in my tank, ones with the greenish tint and all brown, they did spread very fast, i had some success with the boiling water, a thick kalk paste worked better for me but i did not want to overload my tank with kalk so i only would do small areas at a time, then i tried Joes Juice, it worked great, I killed all that i could reach over a 2 day time frame with harming any corals
