COMMON TERMS:

Algae - Microscopic forms of plant life which enter the pool by rain, wind and dust. There are numerous varieties
- some are free floating whilst others grow on walls and in cracks and come in different colours. Some are
more resistant to chemical treatment than others.
Bacteria - The germs that contaminate your pool. Introduced by swimmers, dust, rain storms and
other elements.
Balanced Water - The correct ratio of mineral content and pH level that prevents pool water from being-
corrosive or scale forming.
Chloramines - Compounds formed when chlorine combines with nitrogen from urine, perspiration, etc.
Chloramines cause eye and skin irritation, as well as unpleasant odours.
Chlorine Demand - The chlorine required to destroy germs, algae and other contaminants in the pool.
Chlorine Residual - The amount of chlorine remaining after chlorine demand has been satisfied. This is the
reading obtained with your test kit.
Cyanuric Acid - Also known as stabiliser or conditioner. It reduces dissipation of chlorine by direct sunlight.
Liquid Acid - Chemical used to reduce the pH and total alkalinity in the pool water, and for cleaning
chlorinator Cell.
ppm - An abbreviation for Parts Per Million the accepted measurement of chemical concentration in
swimming pool water. 1ppm = 1mg/L.
