75 Gallon American Bullfrog Tank

I'm not too worried about impaction. He refuses to eat outside of his water. I'm not using a filter initially, might add one down the road. For now I'm just going to change it often. I have a lot of non-amphibian herps/herp experience, and experience with amphibs in a museum setting so I know about filtered/dechlorinated water & all. Have done live vivs before, not sure ill go there this time though.

If you do not want to get into a more complex canister filter right now, recommend take a look at this little marvel: Ovation 1000 Submersible Power Jet Filter. I have one and has worked great in various set-ups. Once water is cycled changing 1/4 to 1/3 of it on weekly basis and rinsing sponge in removed tank water should be enough to keep nitrates down to acceptable levels .
