Backwashing
.
2. Refer to the specifications of the filter media used and implement regeneration
procedures accordingly.
3. Maintain a correct chemical balance of your pool/spa water. The chemical balance
of water is a relationship between its pH, total alkalinity, calcium hardness and water
temperature. The water must be maintained at all times to the following:
pH:
7.2 - 7.8.
Total Alkalinity:
80 - 150ppm.
Calcium Hardness:
150 - 300ppm.
And within these tolerances be balanced to the Langelier Saturation Index within a
range of -0.2 to +0.2.
Note: Testing kits are available to test the water yourself or alternately bring a sample
of the water to a professional pool and spa shop.
