Natural Chemistry's patented phosphate remover is quick and easy to use.  Simply add to skimmer and a thin coating of Phosfree will coat filter media.  As your pool water flows through filter, yucky phosphates are reduced to very low levels.  All other phosphate products on the market will cloud your pool water, but not Phosfree!  The end result is clear perfect water, no waterline rings, no chemical odors and no phosphates.  Natural Chemistry guarantees it unconditionally.
  1. Start with clear, chemically balanced  pool water.  Not sure if it's balanced?  Call the pros at Pool Supply Unlimited for help
  2. Clean or backwash filter if filter pressure is more than 5 pounds over clean pressure
  3. Determine required Phosfree dosage from chart below
  4. Shake up the bottle, confirm filter pump is on, and add required dose directly to skimmer
  5. Run filter 8 hours/day for one week or 48 hours non-stop without backwashing or cleaning filter.

Works very well indeed
It was recommend to me by my local pool store to fix my algae problem, Really works as part of the weekly maintenance, Phos Free is the best brand I have found, I highly recommend this product, Just bought it online because is much cheaper<br>

Love this Product!
We have been battling phosphates in our pool all season, tried everything and nothing seemed to work. Our pool water was always cloudy. Until we tried PHOSfree. Our water is crystal clear and phosphate free.

Phos Free
I followed the directions and saw very little improvement in the phosphate levels in my pool.
