Once I get around to drilling my sump I'm planning to use a movable baffle system like this:

Why don't you use a smaller return pump? You'll use less electricity, add less heat to the water, and resolve the microbubble problem. And you'll reduce your work load by not having to clean out a sponge all the time.
