Spa PHOSfree contains a revolutionary technology, specifically engineered for spas/hot tubs. Add Spa PHOSfree at start up and on a weekly basis reduces and maintains phosphate levels to near zero. Spa PHOSfree reacts with phosphates in the water to render them inert, which leads to their removal by the filter.
Directions for use:
Drain and Re-fill or New Start-Up Add 16oz (4 large capfuls) per 400 gallons (1500L) directly to spa water with filter operating. Temporary turbidity may be experienced with new spa start-up
Weekly Maintenance Dosage Add 1oz per 100 gallon (380L) weekly
