Water Blaster Return Pump

The Reef Octopus Water Blaster pumps are based off the same design as the popular Bubble Blaster skimmer pumps but intended to thrust large amounts of water. These pumps feature a digital control circuit board inside that controls directional start up and RPM speeds.

The smart circuit board will shut the pump off if it detects a problem that could otherwise have shortened the life of the pump. The Silicone Nitride shafts and bearings deters calcium buildup on the rotor unlike ceramic. This means less maintenance and cleaning and more time for you to enjoy your aquarium instead of working on it!

With the performance of these pumps and backing a 2-year warranty how can you go wrong. We offer several different models for water flow and head pressures. 

Note: THIS IS NOT A PRESSURE RATED PUMP. This pump is not ideal for second floor applications or to feed Beckett or downdraft skimmers where consistent pressure is necessary.

Replacement pump for: SRO-CR2000C, SRO-CR2000C, BR2000ss

Sand and lime deposits may increase the wear of the shaft & bearings considerably and may lead to the exclusion of warranty. To maintain efficient performance of the pump, periodic cleaning is required. Thoroughly clean the pump, the drive assembly and the cooling duct in regular intervals, at least once every six months. In case of high lime content, a lot of sediment or failures, shorter intervals may be necessary.

WARNING: Always unplug or disconnect the pump from the electrical supply before servicing the pump, while the equipment is being installed or when being handled. When inserting or removing the pump from the water, always disconnect main electrical plug. Never yank the cord to pull the plug from outlet. Grasp the plug and pull to disconnect. Always unplug an appliance from an outlet when not in use. Never lift the pump by the cord.


  1. Unplug pump from power source and detach pump from skimmer body. 
  2. Clean outside of pump motor body to remove any accumulated debris or buildup. 
  3. Remove volute by unscrewing the Phillips head screws holding it to the pump body. 
  4. Remove and inspect impeller, cooling duct and bearings for noticeable signs or wear, damage, debris or buildup * Be sure to handle the impeller shaft with care. 
  5. Soak pump body and parts in a solution of vinegar and water (50%-50% mix) for a duration or several hours or more depending on the buildup. DO NOT USE DETERGENTS OR OTHER CHEMICALS CLEANERS which could damage the pump or pollute the aquarium. 
  6. Rinse and reassemble the components with care. (You can apply silicone-based lubricant to extend the life of o-rings or gaskets before re-installing.) 
  7. Install pump back into operation and plug into power source.

NOTE: To keep the pump in good working order, always replace any worn parts. The pump motor has no user serviceable parts. If the motor or the electrical cord is damaged, discard the pump. If you have any doubts, contact us or your Water Blaster retailer.
