Installing a durso on the overflow seems like a good place to start. However, this is complicated by the fact that my overflow box is just 2 inches front to back, which makes installing an elbow impossible. I believe that I can make a modified intake out of a 1" mpt X slip adapter, gluing a piece of acrylic over the slip end and then drilling a 1 inch hole in one side that will point down when screwed in. The air intake for the durso can be created outside the tank using an elbow off of the bulkhead and drilling a small hole for the air intake. I've never made one of these before, but it looks pretty straightforward. I also have the added incentive that even a poorly operating durso will be at least an order of magnitude better than my current configuration. The finished product should look something like this (yay MS paint)
