Nice! I use a Rio 20HF attached to 50ft of 1" vinyl tubing to drain my tank out onto the driveway. It takes about 8-9 minutes to fully drain my 220 and sump. I let my aquarium pumps stay on to pump most of the water from my sump up into my tank when I do my water changes.
Pretty neat! I used to drain my tanks with a flexible hose which was very fast, but also very awkward, especially when emptying the hose at the end or moving the hose to the next tank.
