I've been reading a bit about using peroxide to kill algae. I decided to take a few of my rocks out and give it a try. I pulled the rocks out and poured the 3% peroxide on the spots of algae, let them sit for a few minutes, rinsed in ro/di water, and returned them to the tank. Two days later they are looking significantly better. One rock I would like to treat has a rose bubble tip anemone attached to it. My question is how do I treat this rock in particular? Will the peroxide kill/hurt the anemone?
