Hi all,

This is my first post on here although I am not new to keep reptiles and amphibians.

I a creating a new enclosure for my red eyes and this is something I have not done before to this level.

I have purchased an exo terra 60x45x60 (they are currently in a 45x45x60 but this is going to be a new home for some dart frogs.

anyway I really want a water feature (waterfall into a stream that runs into a pond!) but I have some questions as to how to go about this.

I will install a false bottom using egg crate and an internal pump to circulate water from the pond back up to the waterfall/stream.
question is should I have 2 separate water systems or 1. If only one what do I use to separate the substrate from the pond?

This new set up is still just a hobby one but I am looking at trying to breed them so will be installing a rain system also.

Any advise will be well received, thanks,

Scott
