I too am planning something similar, I have a 40gal exo terra for a pair of RETFs, I have made a small pool which will be 5" deep but due to false bottom volume will be about 7 us gallons. I am no searching for some small soft water fish, possibly neon tetras. Will use plenty of carbon, a 600lph powerhead which will pull water through the carbon and supply a stream which will oxygenate and circulate water. or perhaps an external filter?
