UltraKlean™ Pressurized Biological Pond Filter

The Aquascape UltraKlean™ Pond Filter with high-output ultraviolet clarifier and integrated electronic bulb-saver filters ponds, providing pond owners with optimum water conditions and crystal-clear water.
The unique sponge-free design minimizes maintenance and maximizes efficient mechanical and biological filtration. The included biological media packs tightly together, effectively trapping debris.

The high-output UV bulb eliminates single-celled algae which cause single-celled algae (suspended algae) blooms. A bulb-saver timer feature saves bulb life and provides an ideal time to add water treatments.
The simple-to-use self-cleaning feature allows for the unit to be backwashed in less than five minutes without opening the canister or getting your hands dirty.
A cleaning indicator light will automatically remind you when the filter requires backwashing. Aquascape UltraKlean™ Pond Filters come complete with all necessary fittings and carries a 3-year limited warranty.

The Power of the air blower  -   Regular backflushing is required to clear bead filters of waste. Using an Air Blower first to loosen debris makes back-flushing faster, more efficient, and effective.







Saves on electrical costs
Using an Air Blower first to loosen debris allows the backflush to be completed with an energy efficient, low-head circulation pump

Faster back-flushing using less pond water

Agitating the bead with an air blower prior to backflushing reduces the amount of pond water needed to clean the filter when backflushing


Without an air blower, it can take more water and more backflush cycles to clean the filter when only the circulation pump is used.

Improves filtration capabilities

Preventing the beads from clumping together as the filter ages, the Air Blower helps to keep the surface area of the beads cleaner for maximum filtration.

Pro Series Biological Waterfall Filters are manufactured under the rotational moulding process. This method of manufacture offers superior design advantages over other moulding processes, such as injection moulding. The process has a number of design strengths, such as consistent wall thickness and strong outside corners that are virtually stress-free. These attributes are particularly vital for the harsh frost conditions an Alberta winter can through at us.

Pro Series Waterfall Filters and not only help keep your pond clean and healthy, but it is also the ideal start to your stream or waterfall. An inlet hole is located on either side of the Biological Filter, for a convenient PVC pipe connection from the skimmer.

Pro Series Biological Waterfall Filters are buried in the ground so that they are hidden from view with the earth excavated for the pond. A dense filter mat ensures that clean water flows through the high-grade bio-media located on top for beneficial bacteria germination and growth. In addition to this, our Pro Series Biological Filters comes complete with a backflush system which allows you to quickly and efficiently cleanse the biofilter during the season for optimum performance.

You get what you pay for. And what you are paying for is the colonization of billions of more aerobic bacteria in your up-to-date bio media working away hard at eating up all those algae-promoting nutrients. Low nutrient levels result in clean, clear, healthy water that green algae just simply have a very difficult time surviving in. So we are not killing algae, we are just starving it out – naturally.

Pro Series FilterFalls Features:

1. Heavy-duty removable top grate supports rock camouflage

2. Support bars add stability and reinforce the top grate

3. Media bag. (Professional grade & back-flushable friendly Bio-Matrix media sold separately to provide max surface area for development of beneficial bacteria)

4. Dual Bio-Tech filter mats for mechanical  filtration

5. Sturdy bottom grate supports filter media

6. Rolled upper rim provides clean lines and incredible strength

7. 2” or 3” heavy-duty FIPT bulkhead for high flow rates

8. Bottom chamber accepts bulkheads on all sides while bottom cones reduce the surface area for back-flushing

9. One-piece liner flange allows easy, leak-free attachment of FilterFalls to pond liner

10. Solid lip and moulded-in inserts ensure a watertight liner attachment every time

11. Lifetime Warranty
