I had a val that the tops had rotted off from due to lack of light, threw
it in a tank for snail food, and a couple weeks later there's now a good
sized, healthy looking val growing. The plant is actually off from a runner
that shot out from the root ball and not the roots themselves.

This is my actual reason for replying to this since I've had this problem a
couple of times myself. If your driftwood is new, that's definitely it. If
there's nothing living on it such as moss, take it out and boil it in a big
pot (or cut off barrel if it's too big for a pot) and change the water
until it stays clear after a few minutes at a rolling boil. You'll never
have tea water again. If you can't find a way to boil it, get a wash tub or
even a large (clean or new) storage tote, fill it full of hot water, let
the driftwood soak, drain out the water, replace with new hot water, repeat
until the water stays clear. Some people say to use a bath tub, but the
possibility of soap getting into the tank bothers me..
