The water's pH is a
measure of its total acid-alkalinity balance which is the relative proportion
of acids and alkalis in the water or in other
words water that is either too acidic or too alkaline will cause undesirable
chemical reactions. If the water is too acidic, it will corrode metal equipment
causing impressions on the surface materials and causing skin
irritation. If the water is too alkaline, it can cause scaling
on the pool surface and plumbing equipment and can cloud the water. Both high
acidity and high alkalinity alters the effectiveness of the chlorine. The
chlorine won't destroy bacteria as well if the water is too alkaline and it
will dissipate much more quickly if the water is too acidic.
On the pH scale, zero
indicates extreme acidity, 14 indicates extreme alkalinity and 7 indicates a
neutral state. Most pool experts recommend a pool pH between 7.2 and 7.8. To
raise or lower pH simply add acids or alkalis into the water.
Maintaining the proper
balance of chemicals in the pool is a continual process because any new bacterium
shifts the water's total chemical balance.
