Applied Biochemists Filtertrine

The Applied Biochemists Filtertrine is a unique filter cleaner solution that will efficiently remove any buildup on pool filter cartridges, D.E. grids, and sand filters. The filter cleaning solution will turn red when active, and change to orange or yellow once the active ingredients are consumed by contaminations. If a deeper clean is needed, you will simply need to add more product to make the solution red once again to continue fighting the buildup on your filter.

• Use this at spring opening to remove any winter debris
• Use after periods of frequent pool/spa use
• Use every 1-2 months to maintain maximum efficiency
• Clean the filter when preparing for winter
• Compatible with all sanitizing systems
