Alright, I'm brand new to frogs. I am building my set-up right now, and currently have a mostly water set-up with some rock islands for land, and big gravel on the bottom of the water section. I will end up planting some live plants and things like that, but I'm having a hard time picking a filter. It seems like there are so many options. What is the best/cheapest way to get good filtration? (I have been looking at the Tetra whipser, and some other reptile filters) Thanks!
