For guaranteed clear water, ponds and water features need a helping hand. Pressurised filters can be easily incorporated into the supply for a watercourse, waterfall, stream or any water feature. They have the great advantage of being located above or below the water level and can be buried almost completely for discrete installation. With a built-in ultraviolet clarifier and biological action, the pressurised filter really should be a fundamental element in the design and construction of all small ponds and water features.
