My main display has flatworms and bristle worms and I don't want to carry those over to my new frag tank. Rather than buy supposedly "clean" chaeto from somewhere, I was thinking I could just dip some of mine; I have tons as it grows like crazy in my refugium. I have Reef Dip, Bayer, and Flatworm Exit. I have also heard of people doing freshwater dips and putting it in a refrigerator for a day. They might make their way in eventually, but I'm trying my best to keep this new tank pest free. Does anyone have a recommendation on the best method(s)?
