The FiloClear Pressure Filter is a compact all-in-one pond filtration system with a patented Easy-Clean function making it the fastest & most convenient cleaning
mechanism on the market. The built-in cleaning mechanism makes filter maintenance possible in a matter of minutes.
FiltoClear systems & built-in UV Clarifier with bypass for optimal efficiency & low power usage.
The built-in cleaning function of the FiltoClear makes regular cleaning quick and easy.
FiltoClear systems can be installed unobtrusively by burying up to 2/3 of the filter below ground.
Simply turn off the pump, rotate the cleaning switch, pull the cleaning handle a few times to loosen debris, turn the pump back on to flush the filter, then flip the switch back - that easy.

The built-in UV-Clarifier makes the FiltoClear Pressure Filter your all in one filtration solution. From the moment you add the filter to your pond, the UV-Clarifier starts flocculating (clumping) microscopic green algae, which then can be removed very easily by the filter.
Pressurized filters allow for the use of Waterfalls or Watercourses in your backyard pond. This feature allows you to have all the necessary components for sustaining life in your pond while allowing you to use only one pond pump and filter to reach your waterfall.
EASY CLEANING MECHANISM
With a simple rotation of the cleaning switch and a few pulls on the cleaning handle will easily and effectively remove trapped debris inside the filter, without ever getting your hands dirty.

These are invaluable for a pond with heavy fish loads or provide a professional-grade solution for biological filtration where our Filterfalls will not work within the space allocated.
Can be buried up to control head, if desired, for easy concealment
Simple to assemble and set up
Includes Ultimate non-clogging bio media with 750 SSA
Minimal back pressure – high flow rate media creates very little back pressure

PRO SERIES BIOLOGICAL FILTERS
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
