Natural Chemistry Phosfree 2L

Phosphates can become problematic in your spa if left untreated, which is why it’s important to protect your hot tub’s equipment from potentially damaging effects. Removing excessive phosphates reduces grit, grime, and maintenance challenges caused by calcium phosphate scale.

Phosphates can enter your spa water from sources like leaves, decaying plant matter, sweat, and other organic material. Phosfree works to eliminate these bad phosphates to ensure clean, healthy spa water.

Natural Chemistry Phosfree​ is formulated from lanthanum (rare earth) compounds. When added to the skimmer, a thin coating of Phosfree​ forms on the filter media. As pool water flows through the filter, phosphates are reduced to a very low level.

Features:

• Most effective way to remove phosphates prior to using a weekly maintenance product
• Works in the filter (no clouding of the pool water)
• Reduces phosphates down to near zero
• Reduces pool maintenance
• No Phosphates – No Problem

Directions for Use:
This product is designed for use in properly balanced pool and spa water.

1. Clean or backwash filter.
2. Determine appropriate dose. * See chart below.
3. Shake bottle well prior to application. With circulation pump running, add dose to skimmer.
4. Run filter for 48 hours continuously without backwashing or cleaning.
5. After 48 hours of filtering, clean/backwash filter. Retest phosphate levels, and if necessary, repeat steps 1-5.

Note:​ If DE filter pressure rises to 10psi above start-up pressure, turn pump off for 1 minute and then turn it back on. If pressure remains high, backwash or rinse for 30 seconds.

Dose per 10,000 gallons (38,000L)

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.

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