Brown polyps out of control

[trueperc]

I been personally using kalk paste. It been a long process as the little bugger pop up all over the place but I seem to be winning the battle.

I'm using the kalk paste on discosoma mushrooms now. I successfully killed several hundred nuisance yellow colony polyps. Now onto the mushrooms. Here is why. Mushrooms seem to win vs everything

Just an example. They're encroaching on many other Lps and sps corals and causing death and recession

Cubandan - looks like it's been a solid three months since you added the racoon butterfly - how's the tank look today? I have a 210 gallon that is suffering from the same issue. Thanks.
