CE-SPA is a chitosan-based clarifier with added enzymes, specifically formulated for hot tubs and spas. The enzymes remove non-living organic waste and oils; the chitosan attracts particles to be filtered out. Removing organic waste is our Second Pillar of Proactive Pool Care. Hot tubs and spas have warm, agitated water. Normally those conditions cause excess bubbling and sometimes foaming with Orenda enzymes like CV-600 or even CE-Clarifier. CE-SPA Clarifier was formulated specifically for these conditions to minimize the foaming and still deliver the results needed for clean water.
