Thinking of new set-up.
I currently have my little White's in a part aquatic tank, the bottom third is water. I'm hoping (when I can afford it) to get an Exo Terra 18x18x24" viv and make it more terrestrial.
I've been thinking about making a false bottom and having a waterfall-stream-pool effect in the tank. Does anyone forsee any problem with using a undergravel filter to move the water from the bottom of the tank to the outlet/waterfall? I've been looking at how these work and as I understand it an airline to the bottom of the uplift pipe is all that's needed to get the water flowing through.
So the layers I am think are - gravel or those clay balls on top the filter tray, with a corner clear for the pool, top this with a mesh of some kind to stop the substrate going into the water, then the substrate and plants on top this.
The thing is, an undergravel filter usually has water pulled down over the whole surface and in this case the water would be pulled kind of from one corner to the other, if you get what I mean?
Please excuse my VERY crude drawing!
