Cecil, Lusk has also got me interested in adding an RAS feature to the tank. He's going to try to let me know how to recirc some of the water, filtering it along the way, and use the filter to grow snails. That way I could move the snails into the redear sunfish tank that I'm starting for a snack/treat.
Ultimately, I'm just hoping to help my little ponds out by being able to add some primo feed-trained individuals into the system, and give me an option for overwintering redears and oversummering yellow perch. I have had the added benefit of giving my girls something fun to watch, which may be the best bonus of all!
