I have two tanks....One is a reef tank that has velvet and is currently in a fallow period and the other will be a fowlr tank once it's done cycling. The reef tank has some beautiful live rock with coralline algae on it which I'd like to put in the fowlr tank. I planned to use hydrogen peroxide in a bucket 3% and scrub the rocks with a toothbrush. Then I plan to let them soak longer in the peroxide to kill the velvet (whatever life stage it's in). Should this work to kill the velvet and how long should I let the rocks soak in the peroxide? I know from reading peroxide can kill velvet in a tank. All knowledge is helpful from you guys.
