Water Balance

30
The results from a Pooltest 6 can used to determine the Palintest
Water Balance. To calculate this on other models, Tablet
Count tests for Alkalinity and/or Calcium Hardness will be
needed and are available from Palintest.

Procedure

1. Carry out tests for Calcium Hardness and Alkalinity.
For each convert the mg/L value into the corresponding factor.
2. Write these factors in lines 1 and 2.
3. Test for pH and write this directly in line 3.
4. Add the three values together, this is the Palintest Water
Balance Index.
5. Compare this result to the ranges given in the table under
Interpreting the Result.

*Palintest Index is based on 28˚C/82˚F. For high temperature
pools and spas, add 0.1 to the value. For unheated pools and
spas, subtract 0.1.
