Water Chemistry

Luckily for us, living in Florida means we can swim almost year round. Because of our glorious weather, we don't have to shut our pools down for winter, but, we cannot neglect the chemical balance of our pool water. Whether it be winter or summer we need to constantly monitor the conditions of our pool and spa water.


The following guide lines are set out in the order I feel most important.

Ph. Is critical as far as water balance is concerned. If Ph. is out of balance we would have a situation where the pool water is either Acidic or Alkaline. The ideal range for Ph. is between 7.2 and 7.8. Do you know that if a Ph. reading was say 8.0 only 20% of any Chlorine added to the pool would be effective, therefore, 80% is wasted. In this situation it would take 5 TIMES more Chlorine to reach a desired disinfectant level.

Total Alkalinity. Is the buffer that helps keeps the Ph. within the proper range. When this is out of balance like the Ph., it affects the effectiveness of Chlorine to sanitize the pool water.

Chlorine. This chemical comes in several different forms. It may be liquid, in tablets or a dry powder. Depending on which of these are used, knowledge of how each reacts with the other chemicals present in the pool is essential.

Stabilizer. Called Cyanuric Acid (CYA) is the chemical that shields the Chlorine from sun light and is very important in making the Chlorine effective and doing it’s job as a SANITIZER. At the same time it makes it last longer. (Saves you Money)

Calcium Hardness. Maintaining this in the correct range prevents some of the problems in swimming pools. These can be, pitting, etching and corrosion of surfaces and pipe work.

TDS. Total Dissolved Solids.
