Hello, I am completely new to frogs, vivariums, and paludariums. I have a northern green frog we have been nursing back to health, and would like to create a comfortable home for him. I've been reading and watching youtube videos like crazy on set ups, but I still have a few questions:

1) What do you recommend for filtration with a messy pond frog? When I was a kid, I had a fish aquarium with an undergravel filter. It seems this is not commonly used any longer, which leaves me lost on what people usually use.

2) How do you clean a vivarium/paludarium that contains living plants and substrate? And how often does it usually need cleaned if a pond frog lives in it? I have 1 frog and a 30 gal tank.

3) I'd like to create a set up with a water feature and I'd like to be able to remove the pump in the event it quits working. Does anyone have a method they use to achieve this?

Thank you!
