Subject: Service life of Nature II
Q. How often should a spa using the Nature
II Spa Purifier system be drained and refilled?
A. The chemical saturation point
of spa water is measured as Total Dissolved Solids (TDS).
Your monthly AnalyzePlusTM water analysis from Aqua Vita
Spas indicates the level of TDS in your spa water. Total
Dissolved Solids of 1500 ppm or higher, inhibit the ability
of water maintenance chemicals to maintain clean, clear,
spa water. Spa water that is maintained by Nature II Spa
Purifier has a MAXIMUM service life of four months before
requiring a Drain, Clean and Fill or Water Change.
However, if the Total Dissolved Solids rise above 1500 ppm
BEFORE the end of four months, a Drain, Clean and Fill or
a Water Change will need to be performed. Refer to the SpaCareTM
section of the EZCarePlus Manual for these procedures. After
refilling, follow the Start-Up instructions found
in this section.
