The Surge Filter is an innovative filter that helps deliver crystal clear, healthy water for ponds up to 1,320 gallons. The Surge Filter uses K+Media for enhanced mechanical and biological filtration to trap fine particles and to help maintain a biological equilibrium within the pond. An integrated UV Clarifier prevents green water. The Surge Filter is easy to install and is simple and quick to clean, using Evolution Aqua’s patented Air Clean Technology. This unique air syphon design allows air to be drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.
