Natural Chemistry PHOSfree is formulated from lanthanum (rare earth) compounds. When added to your skimmer, a thin coating of PHOSfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to very low levels due to the lathanum and phosphate molecules sticking together. Works inside the filter which means no clouding of the water.

For DE & Cartridge Filters: Do not add more than 1.5L (48oz) at a time. If more than 1.5L (48oz) is needed to treat, be sure to clean or backwash the filter between treatments.

Please Note:Algae must be treated prior to testing and lowering phosphates. Chlorine must be under 5ppm before testing phosphates.

Dose per 10,000 gallons:

• Phosphate level: 300ppb or Less PhosFree dosage: 16oz
• Phosphate level: 600ppb PhosFree dosage: 32oz
• Phosphate level: 900ppb PhosFree dosage: 48oz
• Phosphate level: 1200ppb PhosFree dosage: 67.6oz

- Use at pool closing in the fall to control algae during the winter

- Less filter maintenance

- Less waterline scum

- Less chlorine needed to control algae

Q: What is the dosage?

- 4 oz. per 8,000 gallons (higher dosage for excessive phosphate levels).

Q: What are the directions?

- If pool has algae, follow dealer instructions to treat.

- Follow dealer instructions to balance water chemistry.

- Clean or backwash filter, if necessary.
