Seems like an ok setup.Ill provide some info so you can gather materials and determine what exact route you want to take.

Looks to me like a exoterra tank with a back wall. You can find these on many reptile websites. Ill include a link for you.http://www.joshsfrogs.com/product/15...arium-12x12x18

The eco earth substrate type stuff can be found here http://www.joshsfrogs.com/product/14...rest-bed-giant

The water he has in the tank looks as if it is being pumped with a rock waterfall. In one of the frames you can see the water flowing as if being sucked up by a filter. If you keep water in your tank in a large amount like this, I would recommend using a filter system of some sort. This system could be a False bottom tank (Link shows instructions and clarification)http://www.angelfire.com/sc2/dendrob...s/fbottom.html

you could use the filtration system by a waterfall-http://www.joshsfrogs.com/product/82...ve-reptofilter

When you DONT have a false bottom, the substrate tends to get VERY moist and ends up having to be changed more often.
In my opinion having large amounts of water is difficult when you start caring for frogs.
I recently bought a red eye tree frog and I am going on about 6 months now. I also decided to go with a similar set up. The water looks very cool like this but often it dirties VERY fast. Its also kinda tricky separating substrate and water. I would recommend using a water dish till your more comfortable. Not to mention crickets are very very prone to jumping in the water.... this can be very annoying when you feed your frog only 2-3 crickets and most end up drowning.....

Here is a link to the Red Eye Tree Frog care page. Make sure you read it if you have not already.

Good luck with your frogs. Make sure to take some pics of you constructing your tank. We would all love to see it come together.
