I've been using the Sump Buddy 40 for about a year now. The Mag Drive 9.5 is a good pump for this skimmer. Incidentally, don't use the larger bioballs at all. Even though it's recommended on the website, I've had direct communication with Gary at AE Tech and he told me the smaller bioballs work better with all pumps. The bubbles do not completely fill the box, Only about 3/4. If they did, you'd have too many bubbles escaping into the sump. I elevated my skimmer up about 3" off the bottom by building a platform to reduce any overskimming when the system is turned off and on as the sump water level takes time to settle down when the return pump is turned back on. Another recommendation from Gary.
