Thanks everyone for the words of encouragement and ideas. I didn't mention it, but rainfall was my biggest concern. We've been a little on the dry side for a couple of years now, actually since the warmer weather has started, this is the lowest its been in some time. I could siphon the tank down, then poison it, but then I'd probably have a tad-pole tank for 5 years waiting on rain...

Bluegill stocking sounds like a better alternative to draining, but I don't understand how bluegills will deplete the Green Sunfish population. It seems I'd just be introducting 'another' thing for the greenies to eat! It would give my bass more to munch on, but the greens would get the benefit too, at least on smaller bluegill.

Anyone know where I could buy some 14lb Bass that have been trained to eat green sunfish??

Keep the ideas coming guys, I'm all ears.
