Directions for use:

1. With circulation system on, adjust pool water pH to 7.0-7.2 before adding PHOSfloc- VERY IMPORTANT 2. Add 4lbs (or required amount) of PHOSfloc to a large bucket or water and mix. If you pool has a recirculation (filter bypass) setting, add PHOSfloc/water mixture slowly to skimmer and allow water to circulate for 1 hour. Do not add directly to filter. Turn system off and allow PHOSfloc to settle (this may take up to 12 hours). VACUUM SEDIMENT TO WASTE (do NOT vacuum to filter) OR If no recirculation (filter bypass) setting is available, add 4lbs of PHOSfloc to a large bucket of water and mix. With filter system off, broadcast this mixture over the water while walking around pool. Allow PHOSfloc to settle (this may take up to 12 hours). VACUUM SEDIMENT TO WASTE. Do NOT vacuum to 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 Important: Always make sure enough PHOSfloc is added to pool versus the amount of water in pool (eg: A 20,000 gallon (75,000L) pool must have 2- 4lbs containers of PHOSfloc added). If not enough PHOSfloc is added, the product will not floc properly.
