This is the pump I use on all my aquariums, and the main benefit for the reef is that each one is plugged into a Battery Backup by Ecotech. This battery keeps the pumps running for as long as 24 hours. Maintaining flow in your aquarium during a power outage is the difference between life and death of livestock. That's why I trust Vortech pumps. They run silently, take up no space in my aquarium, and keep the cords out of sight.
