Ok, I've ordered plants for the first time from an unknown source, so I have no idea what the plant could be bringing with it. Is there any procedure I should use to make sure it does not introduce anything nasty to my tank?
There is a potassium permanganate dip out there that is supposed to be good... but if you don't have that (as you probably don't have on hand ;D ) then you could do a 2 or 3 minute dip in a 1 part bleach 19 parts water solution. That should work for most hitchhikers and is a lot cheaper.
Cool, thanks for the replies. I looked up the potassium pomegranate stuff and apparently Jungle Clear Water is made with it which both Petsmart and Wal-mart carry. So, I went and bought some of it. Didn't hurt my newly arrived anubias at all.
The only problem I had is that the roots were in some kind of clay/silicone stuff that I could not remove no matter what I tried. I let soak for a long while, I am just hoping that substrate concoction they used doesn't have any nasties in it.
