The use of algaecide to prevent or destroy algae
is often recommended. Its use, however, can result in water foaming, a
change in total alkalinity
and pH, and an increase in TDS.
Cheaper copper-based algaecides can cause water dicolouration, staining
of the pool walls and floor, and green hair and fingernails (see
copper for more information). Algaecides that contain isolated (chelated)
copper are desirable, though they tend to be quite costly. With the use
of various sanitising units available, such as the Pool
Wizard, algaecides are not necessary. If you use an algaecide, follow
the manufacturer's directions.
