Lol, I don't even want to say..... I have been changing one to two times a week with four of the little pigs in there. Also the gravel I had before compounded the problem by trapping all the solids, then when got stirred up it would clog the filter. I changed to the bigger cannister about two weeks ago and its been a little better. We'll see how it does w/o the gravel.

The frogs love the water (imagine that...lol), but I don't know if it adds any well-being or health benefits. They are bullfrogs on the other hand so I think water that is a little deeper is beneficial to their happiness. Ultimately I like setting it up and it is more aesthetically pleasing. I would recommend a nice setup but keep it simple too. They will dig up your plants and smash them down so keep live plants simple. Start with a big cannister. I had to learn the hard way. I've gone through three different ones prior to the big one I use now.
