Hi Guys, new to R2R, but a long time lurker. I have been using this overflow for about 2 years now with no trouble, so I figured it was time to show it off! It will overflow about 2-300gph to my sump, and will automatically start and stop when the water level rises above the baffle just before the drain. When I first set it up, I had intended to use a aqualifter pump to keep bubbles from accumulating, but found that a syringe and 2 check valves is more that capable with a pump once every few weeks. It does stick out pretty far because of how I decided to make it, but I have a design for a lower profile option. With this any IM AIO can be made to use a sump! I even put a brick in the old return pump pit. If anyone feels like this is a device they need for their tank, I have been considering making a number of them, and the more I make the less cost per each!
sorry about the lighting, forgot to turn off my plant lights!
