Seems like every time I give my Pacman a bath, he fouls the water good. Obviously if he defecates, the water is fouled.

But i've noticed that even if he does not take a **** during his bath...about four hours later I see the water has clouded with bacteria.

My frog does not seem to have a health problem, but put him in fresh water for a bit. That water is AWFUL in short order.
