How To Include A Pond Filter Inside A Waterfall (Filter Fall)

Remember what I've said numerous times ... a pond filter is nothing more than a place to biomedia so that millions and millions of bacteria can be provided with surface area to cling to (the more surface area the better because then you can grow more bacteria). When pond water is circulated across this biomedia the bacteria in the pond filter consume the ammonia impurities and convert them to nitrate fertilizers for use by plants in a pond.

To make a pond filter less obtrusive it would be a good idea to include a pond filter within a waterfall or stream if possible. Well here's one of those products for you if the idea of a waterfall pond filter appeals to you ...

A clever way to include a bio fiter system into a pond with a waterfall is to use a Filter Fall. The water from the pond pump runs through the Filter Fall which contains biomedia and overflows back into the pond via a lip or spillway. The width of the spillway determines the waterfall flow that the system can handle best.

Atlantic Pond Filter Falls include a chamber through which water flows up. The chamber has a filter mat which traps solid particles. After the solids have been removed water flows through the bag containing the biomedia and then out over the spillway. The ideal pond bio filter media is Alfagrog also called Supra in USA . The filter fall system has advantages over a conventional pond filter ... not least of which is that it can be made part of a waterfall system.

• Filter fall that can handle 1200 gph of water flow over waterfall spillway

• Filter fall biofilter for flows up to 2,000 gph over spillway

• Filter fall for flow up to 4,000 gph over waterfall spillway

•  Filter falls for water flows up to 6,000 gph over spillway

• Filter Falls for flows up to 10,000 gph over spillway

• Filter Falls for flows up to 15,000gph over waterfall spillway

Each unit includes bulkhead, grate, biomedia bag, and filter mat.

Good Pond Filter Design Principles In General

 A filter will do a good job if there is a way removing solids effectively and of colonising large surface areas of bacteria that are able to intimately contact the water containing the waste products pumped through the system and if there is continuous flow of oxygenated water through the biofilter we tend to use the word filter as a short version of biofilter. The more surface area that can be incorporated into a filter the better. An attempt (albeit a basic attempt) to achieve this is by placing hollow tubes of rough plastic inside the filter box. Other attempts include the use of orange bags, lava rock, tubes, and even hair curlers.
