Yeah, I think that's most likely the case. Before, I was never careful about sanitizing my plants when I received them from other people or through websites cause I was too eager to plant right away. Kind of makes me glad I got good planting tongs instead of digging my fingers into the substrate. Now I pot perm dip all new plants. :thumbsup:

and I assume the potassium permanganate is shrimp safe?
