The sump/filter area of my savannah monitor enclosure in photos...
The pool is connected to the sump via a gravity siphon (overflow). The water is then filtered out of the sump and pumped back into the pond. The system has a total water volume of 40 gallons (the pond is 20 gallons and the sump is 20 gallons).
That Mopani driftwood is no longer in the pond. Apparently the rule about burrowing under heavy objects applies to water features too.
20 gallons of water weighs roughly 175 pounds. I didn't want the pond sitting on the substrate, thereby creating a crushing hazard, so the pond is fixed to a shelf.
