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
11. Lifetime Warranty
