That's what I ended up doing! I tweaked the formula a little bit (mostly using less charcoal since I agree with theories that it can be harmful) and filled a 5 gallon bucket with my substrate mix!

I have all my plants from Josh's Frogs along with my own ficus and two Crypts all in net cups planted with my ABG mix (this is to keep them going good until our terrarium is ready for them)

We heard back from the tank lady, got some pictures... It's a 120 Gallon Breeder, which will work better for us! 48in long, 24in tall and 24in wide.

Have to pick up some spare bags of Hydroballs and on Saturday when we get the tank, it'll be time to start work on the background!

I'll have pictures of all this stuff up soon!
