If rock can be taken out of tank, use H202 and apply with a tooth brush. Let set 5 minutes and brush off and wash before returning to tank.

Hydrogen peroxide is collateral damage to everything when used as a concentrate with a tooth brush. I also use it as a 10 minute dip. Mix a 10% solution of H202 with tank water. In some cases I have had to dip twice.

Both techniques work, however, coral can be damaged if applied incorrectly.
