The Red Dragon pump from Royal Exclusiv has been a run away success in the reef aquarium hobby, partly due to the tremendous air flow rates you can run with the pumps. However, lets not forget about the sheer raw power these pumps have at pushing water which any fire-fighter is sure to respect. Red Dragon II pumps are so good in fact that its best if you just see the pump in action as demonstrated in this video. The flow rates are being controlled by the Ocean Simulator controller which was detailed out a few months ago. But are these pumps worth their high price tags? To some they are and for the lucky owners who own one they just ask one question. Got flow?
