hey guys, I'm Fran from South Africa, and I'm new to frogs.
So I'm getting some pdf's in a few month's time, and thought it's best to start building some vivariums , I'll be using 29gallon(110L for us metric system users) aquariums converted to vivs. Anyway the question I would like to ask, Is it important to have a pump or filter circulating water in the vivarium? I'll be using false bottoms ,with PVC access tubes hidden in the background for maintenance (water changes), and then just hand mist. If I establish the plant life way I advance of adding frogs, would that aid in preventing the water from becoming stagnant? To me a pump just seem nosy and kinda unnecessary, it makes sense to me that simple systems have less things that can go wrong down the line?

Apologies if this topic has already been discussed in another thread, but I could not seem to get any definitive info on the topic.

Thanks guys
