when my last tank, a 37g, got infested with fin rot and other nasties I couldn't get rid of, i wanted to be able to use some of the plastic plants and such for my new tank, 55g.
i used a full strength bath of peroxide to clean them and the nets. i then let them sit for 2 weeks before putting them in the new tank. granted, i let the tank cycle for a month before new fish, but i felt peroxide was safer than bleach for disinfection. it will completely evaporate and become inert. i don't know that i would put it IN my tank with live fish, tho!
BTW...QuickCure will kill snails. Course, if you don't have a reason for using it, you shouldn't.
