I've found quite a few types of plants in my creeks and stock pond here on the ranch, that look promising as aquarium plants. I would like to send them to a couple people for positive ID and then trade them in the Swap N Shop. Before I do that, I'd feel more comfortable treating them somehow, dipping them, to make sure I don't pass on something nasty. What's the best way to do that? Bleach water? Hydrogen peroxide? Potassium permaganate? All three? What strength of each should I use (as in "X" parts of each added to "X" parts of water)? How long should I submerse the plants in each?
