Performance Upgrade Diffuser Station can increase water flow by up to 30%. The diffuser uses an easy to assemble, self-weighted, stainless steel base that lands upright every time. The built-in strain relief is infinitely easier to use, with no hardware required, while providing the same holding strength. In addition, custom edge guards are included to protect lined ponds. The updated diffuser heads can easily be integrated into older systems with no issue or difference in performance.
