I have always wondered what pool chlorine tabs would do, I heard a story about a few neighbors that were feuding over some kind of control over a shared body of water and the one guy dumped a bucket full of pool chlorination tabs in the water and killed every fish in it.
May be a wives tale but they don't survive in chlorinated water, no? and the chlorine would dissipate with time, no?
Ive been contemplating trying it on a little pond here local that is overpopulated with bullheads, the owner doesn't care what gets done with it, we been going there and catching a bunch of the little bullheads for trot-line baits, but they are damn near too stunted for that, or at least we'd love if they were about twice as big as they are now.
Just thinking out loud here.
