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

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
Sanitiser Cell.
ppm
An abbreviation for Parts Per Million the accepted measurement of chemical
