Description

Phosfree is the most effective way to remove phosphates from your pool water before using a weekly maintenance product. Simply pour Phosfree into your skimmer and it will immediately coat your filter media, reducing phosphates in the pool water as it passes through the filter. Phosfree works strictly in the pool’s filter so there will be no clouding of the pool water.

Directions for Use:

  1. Balance pool water chemistry.
  2. Clean or backwash filter.
  3. Determine dosage *See Chart Below
  4. Shake well before use.  Add correct dose to skimmer with the pump running.
  5. Run pump continuously for 48 hours.  Do not backwash or clean filter during this 48-hour period.
  6. After 48 hours, clean or backwash the filter.  Retest phosphate levels.  If necessary, repeat steps 1-5.

Note: for D.E. filters, if pressure rises 10psi above start-up pressure, shut off pump for one minute and then turn it back on.  If no change in pressure, backwash or rinse for no more than 30 seconds.

Chlorine must be under 5ppm before testing phosphate levels.
