Gravity Pond Filters

A gravity-fed pond filter is the preferred choice for serious pond keepers, especially those with heavily stocked koi ponds, due to its unmatched capacity for biological filtration and high flow rates. Unlike pressurised systems, water is typically fed into a pond gravity filter box by a pump, passes through the media and any integrated UV clarifier (for green water control), and then returns to the pond by gravity. The major benefits of a gravity pond filter include superior oxygenation of the filter media, extremely simple maintenance access, and the ability to house large volumes of biological media, which are crucial for breaking down high levels of waste. This design results in the most stable, healthiest, and clearest water quality possible for large or specialised koi setups. Shop for your perfect gravity-fed koi pond filter today at DLP.
