Reef Octopus Water Blaster Circulation Pump
Similar to the well-known Bubble Blaster skimmer pumps, the Water Blaster pumps are made to propel massive volumes of water. These pumps have an internal digital control circuit board that manages RPM rates and directional start-up. If the smart circuit board notices an issue that may have otherwise reduced the pump’s lifespan, it will turn the pump off. In contrast to ceramic, Silicon Nitride shafts and bearings prevent calcium accumulation on the rotor. Thus, your aquarium will require less upkeep and cleaning, giving you more free time to enjoy it. How can you go wrong with these pumps’ performance and a 2-year warranty? We provide a variety of water flow models
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.

The Water Blaster HY-12500w pump offers super efficiency and performance.

Energy Efficient – Compared to other traditional pumps, Water Blaster pumps use less energy and are more efficient. Has little to no impact on the water temperature in your tank while operating at a reasonably chilly temperature.

Bubble Blaster ImpellerSilicon Nitride Impeller – Silicon nitride is used to make the shaft and bearings of the impeller. Unlike other ceramics, silicon nitride is extremely wear-resistant and prevents calcium buildup. Consequently, less maintenance is required, which increases operational life.

Digital Circuit Board – The direction of start-up, RPM speeds, and an automatic shut-off feature if the Water Blaster senses a fault are all controlled by the digital control circuit board.

2 Year Warranty – Enjoy piece of mind knowing that Water Blaster pumps are covered by a 24-month warranty against faulty manufacture and defective materials.

The following pump IS NOT pressure-rated. For applications on the second floor or to feed Beckett or downdraft skimmers where continuous pressure is required, this pump is not the best choice.

*Under normal usage, the product is guaranteed for two years from the date of the initial purchase against manufacturing or material flaws. This warranty is in effect as of the date of retail purchase and is non-transferable. To serve as documentation of purchase, kindly save a copy of your sales receipt. The manufacturer reserves the right to repair or replace the Bubble Blaster pump. Any Bubble Blaster pump that has been subject to abuse, carelessness, tampering, or unintentional damage is not covered by this guarantee. No liability is assumed with respect to loss or damage to livestock or personal property irrespective to the cause thereof. Failure caused by misuse is not covered by this warranty.


The shaft and bearings may wear down significantly as a result of sand and lime deposits, which may result in the warranty being voided. Periodic cleaning is necessary for the pump to continue operating efficiently. At least once every six months, thoroughly clean the cooling duct, drive assembly, and pump at regular intervals. Shorter intervals could be required when there is a lot of silt, a high lime concentration, or failures.

WARNING: Before servicing a pump, installing equipment, or handling a piece of equipment, always unplug or disconnect it from the electrical supply. Always unplug the main electrical plug before entering or withdrawing the pump from the water. Never take the plug out of the outlet by pulling on the cable. To detach, grasp the plug and pull.  Always unplug an appliance from an outlet when not in use. Never lift the pump by the cord.

Detach the pump from the skimmer body and unplug it from the power supply.
Clean the exterior of the pump motor body to get rid of any accumulation or dirt.
By removing the Phillips head screws securing the volute to the pump body, you may remove it.
Remove the impeller, the cooling duct, and the bearings to check for any obvious wear, damage, debris, or accumulation. * Take caution when handling the impeller shaft.
Pump body and components should be submerged for a number of hours or longer, depending on the amount of accumulation, in a solution of vinegar and water (50%-50% mix). Use of detergents or other chemical cleaners, which might harm the pump or contaminate the aquarium, is NOT RECOMMENDED.

Carefully clean and reassemble the parts. (You can apply silicone-based lubricant to extend the life of o-rings or gaskets before re-installing.)
Plug a power supply into the pump and reinstall it in service.
NOTE: Always repair any worn parts to maintain the pump functioning properly. No components of the pump motor may be repaired by the user. Throw away the pump if the motor or electrical wire are damaged. Contact us or your Water Blaster merchant if you have any questions.
