If I am reading this correctly, you want to build a 100g tank, with live plants, with an automatic misting system so you can keep maintenance down, for a budget of $300, including the frogs? Sorry to be the bearer of bad news, but that is not going to happen. It's just not possible. The misting system that you would need for that size tank alone will eat most of your budget. The monsoon is fine for small vivaria, but for 100g, you are going to need something along the lines of http://www.mistking.com/ultimate-misting-system.html with an added head. An ultrasonic fogger will be useless in that size tank unless you are only using it for aesthetics.

My suggestion? Stick with the fish for now and save, save, save.
