Applied Biochemists Resist 406803

No Testing Required! Resists against stains and scale forming by preventing the minerals in the water from reacting to create stains and scale. Used during swimming pool filling and on a regular maintenance schedule, this long-lasting sequestering formula prevents damage to equipment and swimming pool surfaces typically caused by stain and scale formation.

Features: Long lasting protection against stains, scale and rust
Prevents colored water
Protects equipment from corrosion
No testing is required.

Applications:
Normal:
Use 16 oz. RESIST per 10,000 gallons of swimming pool water. For hard water, (over 200 ppm), high iron, copper or manganese content (over 0.1 ppm), double the initial dosage (32 oz. per 10,000 gallons).
Add RESIST after the swimming pool has been filled. Filled swimming pool should then be circulated overnight before adding chlorine or other swimming pool chemicals to allow RESIST to react with and prevent precipitation of minerals in fresh fill water.
