Types of Filtration

Filtration is a key component in owning a water garden. When buying a filter, select one that is rated for your pond size or larger. If you have a heavier debris load due to an overpopulation of fish or a nearby tree, you may want to consider getting a filter one size larger. Remember, you cannot have too much filtration, but if your filter is undersized you will likely continually battle algae.

Filtration Options

There are two types of filtration: mechanical and biological. Mechanical filters remove debris, such as algae mats and leaves. Biological filters provide a place for beneficial bacteria to colonize and remove nutrients. Whether you are upgrading an existing pond or trying to pick out which  pond kit you want, it is important to consider the different types of filter systems so you can build your ideal outdoor oasis.

  • In-Pond Filtration Systems: The Pond Guy ClearSolution Generation 2 Filter is an excellent option for ponds up to 1,200 gallons. This unit houses mechanical and biological filtration media, a UV clarifier to combat discolored water, and pump to circulate the water. As an added bonus, the water can discharge through an included fountain – with 3 options for patterns – or a diverter valve to power your waterfall or spitter.
  • External Pressurized Filter: For those with larger ponds up to 4,500 gallons, the AllClear G2 and SolidFlo G2 Combo Kits offers mechanical and biological filters and an ultraviolet clarifier in one efficient, economical filtration unit. Water passes along an integrated UV lamp, then through the mechanical & biological filtration stage, consisting of foam filters and media that intercept and trap dirt and debris. Also, beneficial bacteria will harbor here to help keep the water clean and clear. Filtered water finally returns to the pond and the process is repeated. Additionally, this filter has back flush feature, so cleaning is as easy as turning two dials. When setting up this system, place the SolidFlo G2 pump in the deepest portion of your pond away from your waterfall or discharge. If possible, bury the AllClear G2 to keep your filter stable and help camouflage it.
  • Skimmer Boxes: If your pond gets a lot of leaves or you have a high-volume pump you want to hide, skimmers are a practical option. Elite Skimmers can filter up to 10,000 gallons and are compatible with pumps up to 20,000 GPH. These units are a perfect option for your mechanical filtration and are equipped with a large debris net and Medium Density Matala Filter Media Pad. For best results when using a skimmer, place it across from your waterfall or discharge so your pond can circulate properly.
  • Waterfall Filter Boxes: Waterfall filters are a wonder-fall way to incorporate filtration into your pond. The Pond Guy ClearSpring Mini Waterfall Filter, for example, houses BioBalls and two filter pads of varying density for maximum filtration. Choose between two included weir options – a traditional smooth sheet-like surface and ribbed pattern – to get the look that best fits your aesthetics. You can even plumb multiple boxes together via FPT inlets located on both sides of the waterfall box.

    Be sure to select a waterfall filter and not a waterfall spillway. A waterfall spillway simply gives water a place to pool to create an even flow of water and does not provide space to incorporate filter media sufficient to filter a pond, though they are perfect for adding a waterfall to a pond that already has filtration.

Whether you are looking to upgrade your existing filtration system or starting from scratch in a new pond, a properly sized filtration system improves water quality and is a great investment in your pond.
