If you can find a buck's worth of wheat pennies, or older Canadian ones, drop
them in the tank.  Don't do any water changes until the hydra lay over.  Pull
the pennies out, wait a day to make sure the critters are dead, then change
25% of the water.  Remove any chost shrimp, snails, or any other inverts in
your tank first.
