One 4 lb. pail of PHOSfloc will reduce 4,000ppb of phosphates to approximately 600ppb in a 10, 000 gallon pool. The recommended test kit below will test ppb from 0 to 2500 ppb.

H2O# 3648200

Phosphate test kit for professional use,
2 Vial Containers with 50 strips per vial plus one test tube.
 

1. Adjust pool water pH to 7.2 before adding PHOSfloc.

2. Add 4 pounds (one container) PHOSfloc to a large bucket of water and mix. ( Depending on size of pool and phosphate level, repeat as necessary ) If pool has a recirculation ( filter bypass ) setting, add PHOsfloc/water mixture slowly to skimmer and allow water to circulate for 1-2 hours. Must not run through the filter. Turn system off and allow Phosfloc to settle, this may take up to 12 hours. Vacuum sediment to waste.( not through the filter )
Or
If no recirculation (filter bypass) setting is available, add 4 pounds of PHOSfloc to a large bucket of water and mix. When filter system is off, broadcast this mixture over the water while walking around the pool. Allow PHOsfloc to settle, this may take up to 12 hours. Vacuum sediment to waste. ( Not through the filter )

3. Important! It is necessary to further reduce phosphate level to near zero by using PHOSfree.

4. Continue to maintain near zero phosphate levels all season long with Pool Perfect+PHOSfree for easy weekly maintenance. Monitor phosphate levels and keep between 0 - 100ppb. Normal sanitizer levels will prevent algae growth...guaranteed!

Recommended Dosage: Requires phosphate test

The recommended test kit below will test ppb from 0 to 2500 ppb.

H2O# 3648200

Phosphate test kit for professional use,
2 Vial Containers with 50 strips per vial plus one test tube.
 

1. If pool has algae, algae should be treated before continuing with PHOSfree.
2. Pool water should be in proper balance chemically before continuing with PHOSfree.
3. Clean or backwash filter, if necessary.
4. Refer to PHOSfree product chart for dosage.
 

Dose per 10,000 Gallons ( 38,000 L )
PHOSPHATE LEVEL ( PPB )	PHOSfree
300 or less	0.5 L or 16 oz.
600	1 L or 32 oz.
900	1.5 L or 48 oz.

5. With filter running, shake bottle well, and add required dose directly to skimmer.
6. Run filter 8 hours a day for one week or 48 hours continuously without backwashing or cleaning.

When phosphates levels are 100ppb or less, begin Pool perfect+ Phosfree as a weekly maintenance.

1. Shake well before using - contents settle.
2. Each week, with filter running, simply add to your skimmer 1 capful per 8000 gallons ( 30,000L ) of pool water. For example, two capfuls per week will treat a 16,000 gallon( 60,000L ) pool. This bottle treats 64,000 gallons ( 240.000L )
