BEST POND FILTERS. You must choose the right pond filter after going through the pond filter reviews as discussed below: XtremepowerUS 10000 koi Pond Pressure Bio Filter UV Sterilizer: This sterilizer comes with a great specification of 10000 liter per hour which is suitable for a pond with a capacity of 400 gallons.
A very popular choice of pond filter, providing both pond filtration and water clarifying benefits. This pond filter is similar to the basic box filter above, but comes with a UV light bulb which works to remove green water (algae) during the filtration process. This type of pond filter should function almost identically in terms of filtration as a regular box filter, but the added UVC means green water will not be a problem.
A pond waterfall filter works the same as a regular box pond filter in terms of filtration (see our filter article for more info), with both types of filters being interchangeable in most situations. The design of a waterfall filter, however, allows your pond water to flow in a wide arc back into your pond, creating a great waterfall effect.
