I have read here that the bleach dip will kill any parasites. You may not think 2 minutes is long, but bleach is pretty caustic.
I have never had ich introduced from plants I dipped in bleach. I *have* had ich introduced with plants I did not bleach dip.
I have not had the following plants die from a bleach dip: vallisneria caulescens, hornwort, jungle val, apongeton caupronii/udalus, java moss (wilts a bit, but comes back in a week or so), java fern, cabomba, anacharis, millfoils, onions, clover, microsword, glosso, rotatla, anubias, melons, amazon swords, cyperus helferi (I forgot about it and it was in the dip for TEN minutes. Dang plant didn't even flinch) and . . . lights are off in my all my tanks now, so I can't get a look at what I put in there
Do a search in here and see if there are any older posts on bleach dips. I'm pretty sure there are, because that's where I got the idea from months ago.
