The frogs are settled in a 10gallon for now but the viv is well under way. I found the perfect rock to top my waterfall feature. The rock will be depressed further below the top of the cork falls to act as a sort of pond buffer (pump filter flow is a little quick) this will prevent my flow from flying off the edge and instead flow down the walls.
This is my pump housing, there are two layers of eggcrate for the top portion. The first removable top will be wrapped in liner to hold substrate layer and to somewhat keep in tact when it needs to be lifted for monthly filter access.
