HBV-21 Koi Pond Filter Backwashes
With Less Water:

The vertical backwash lateral jet inside the HydroBead™ Vortex HBV-21 koi pond filter reduces backwash time which results in less water use and eliminates the backwash “dead-zones” that occur within other brands of bead filters that feature horizontal backwash laterals.

The HBV-21 medium koi pond filter’s unique design eliminates the need for expensive, difficult to use, and aggravating air blowers that competing bead filters require for backwashing.

Polishes Water for Maximum Clarity and Shine:

The super lightweight Styrofoam HydroBead™ media inside this 21″ bead filter cling together under pressure to trap fine particulates down to 100 microns and polish the water during filtering. The HydroBeads™ easily separate during backwash to release the trapped particulates.

Bead Filters That Require Air Blowers
for Backwashing Are Less Efficient
and Have a Higher Cost of Ownership
than HydroBead™ Vortex

• Their designs don't let them backwash with just water
• They use bio media that doesn't backwash with just water
• Their bio media is either heavy,  porous, or both
• Their bio media "clumps" together
• "Clumping" bio media must be broken up with high air pressure bubbles
• Air blowers add to the cost of the filter
• Air blowers require additional steps for backwashing
• Additional steps mean more time to backwash
• Air blowers require additional plumbing
• Additional plumbing increases installation time
• Air blowers fail over time and must be replaced
• Replacing air blowers increases the cost of ownership
• Air blowers are loud
• These filters are an eyesore in the landscape
• These filters ruin the natural look of the pond

There are many brands of koi pond bead filters that require air blowers for backwashing. The air blower sticks out like a sore thumb on the filter. These air blowers are very loud - more than triple that of a hair dryer. 

Do YOU want to have to wear ear plugs just to backwash your filter?
 We don't think so.

Also, do you want to look at a filter like any one of these near your beautiful koi pond?  Many people build a shed to hide these filters - that also adds to the cost of the filter! Building a filter shed also increases your installation time - and requires additional pipe.  Yup, you guessed it! That significantly adds to the cost of the filter too! If you don't build a filter shed - do you want to scare your fish with a loud air blower?

If you don't build a filter shed you'll also make every dog in your neighborhood bark every time you backwash your filter. Your neighbors won't be too happy with you. 

The Question to Ask is: Why is an Air Blower Required for Backwashing?

The answers we found after testing and researching these types of bead filters is simple:

• 
  They have flaws in their overall design
• They have design flaws in their water flow
• They have design flaws in their water direction
• They have design flaws in their bio media
• The bio media is heavy
• The bio media is porous
• The bio media clogs
• The bio media clumps together
• The bio media is hard

Now, not every filter has all the above, but if it requires an air blower for backwashing, you can be sure that it has at least one or more of these problems.

• 
  Down flow water direction during filter mode traps debris on top of  floating bio media - requiring an air blower to force high pressure air bubbles up through the media to lift the trapped debris to purge it from the filter
• 
  Heavy - or sinking bio media  such as glass beads or clay beads require downward water flow during filter mode that results in the same backwashing requirements as floating bio media in a down-flow design.
• 
  Porous bio media requires high pressure air bubbles to dislodge debris trapped within the bio media
• Ring type and bio-ball type media clump together requiring high pressure air bubbles to break them apart.
