The new Reef Octopus Water Blaster HY-16000 pump is the latest design in the series that started with the Bubble Blaster skimmer pumps but designed for moving water for circulation in the aquarium. The Water Blaster HY-16000 is the largest pump the company offers moving up to 16,000 liters (approx. 4,227 gallons) per hour. The Reef Octopus Water Blaster pump features a digital control circuit board inside that controls directional start up and RPM speeds and will shut the pump off if it detects a problem. The company is also using silicone nitride shafts and bearings claiming it will not let calcium adhere to it like you find with ceramic shafts and bearings. The pumps feature 1 1/4 in. inlet and outlets with union fittings for a quick connection. If you want one of these bad boys, they are running around $360 each.
