Swimming Pool and Spa Care Hints
Perfect Water Factor Ranges

The following ranges are listed in PPM (parts per million). This is the same a Milligrams per Liter (mgL). The chemicals are also arranged in the proper order of adjustment from top to bottom. In other words, don't try to adjust the PH before you have the Total Alkalinity in the Perfect Range.

You will have a Perfect Pool or Spa if you maintain these levels and follow basic routine maintenance.
