I've been doing some reading and they are also not considered reef safe. Will eat clams and soft corals.

Has anyone tried treating with hydrogen peroxide full strength outside of the tank?
I used 50/50 peroxide/tank water mix of the standard 3% solution a while back when battling my hair algae outbreak. All the corals and zoos bounced back within a few hours but my clove polyps stayed closed little specs for almost a week. This was after only a 2 minute dip.

Someone mentioned aggressive use of activated carbon (I think) in that thread about cloves not too long ago.
Cloves don't bother me. if i need to get rid of them, tooth brush always works very well and fast if i need a spot or want some other coral to get some room.

Why are blue cloves considered bad?

They can/will quickly grow in plague proportions, covering every bare surface in the tank.

Do they kill things? Or over take other corals?
Do they just cover the rock?

I've been reading,and apparently Panacur or Safe-Guard are suitable alternatives to fluke tabs. (dewormer)
