Pro Series Biological Waterfall Filters are manufactured under 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, it is also the ideal start to your stream or waterfall. An inlet hole is located at on either side of the Biological Filter, for convenient PVC pipe connection from the skimmer.

Pro Series Biological Waterfall Filters are buried into the ground so that they are hidden from view with 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 back flush system which allows you to quickly and efficiently cleanse the bio filter 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 results 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.
