I have a waveline running 10ft up to a 180 and 120 for 9 months and have been happy with it. Reef Life Support Systems
Ecotech is now making a dc pump and I can't believe it won't be awesome, but expensive. Even Jabeo makes a dc pump that is suppose to work good(no experience with it though). I had a reeflo marlin (which was way overkill) and a diablo dc (I replaced it with the bigger waveline, but kept it as a backup pump).
