Natural Chemistry PHOSfree Directions for Use
PHOSfree is designed to remove phosphates through filtration by applying a coating to the filter media. Depending on the phosphate level, more than one dose may be required. Important: Do not add more than 1L (32oz) within a 48 hour period. Phosphates need to be lowered to 100ppb or lower before beginning to use Pool Perfect+PHOSfree on a weekly basis.
If pool has algae, visit your nearest Pinch A Penny for directions on treating it
With filter running, shake bottle well, and add required dose directly to the skimmer. Note: If DE filter pressure rises above normal range, bump filter per manufacturer's instructions and restart (if the pool filter manufacturer does not provide bumping instructions, turn off the filter for one minute, then restart. If pressure does not drop, place the valve on backwash for 5-10 seconds, turn the filter off, rinse briefly, and restart). Repeat until pressure stays in normal range
Run filter 8 hours/day for one week or 48 hours continuously without backwashing or cleaning.
