I know that WTFs are notorious for dirtying their water, but I was offered something that I cannot refuse. I work at a pet store and the woman that has been heading the reptile department for 20 years just offered me an Exo-Terra Waterfall for my frog tank.

Has anyone used one of these with their WTFs? If so, how long has it lasted? Any tips on keeping it running for a looong time?
