sterilizing

  1. Regular sterilizing of tools?

    Beginner Freshwater Aquarium
    I have a highly contagious worm in the tank right now and read that I need to sterilize all nets, siphons and other tools after every use. I have no idea what I can safely use to do this since I know that soaps, bleach and chlorinated water can all hurt my already sickly fish. Any suggestions...
