Algae
Microscopic plants deposited in outdoor spas by wind, rain and
dust. Causes clogged equipment, slippery surfaces and green water.
Bacteria
Microscopic organism that can cause bather infection and irritation.
Control with chlorination or bromination.
Bromine
A sanitizing agent that kills algae and bacteria in a spa or hot
tub.
Bromine level or residual
After spa water has been sanitized, the amount of bromine left
over to kill new bacteria entering the spa.
Chloramine
A substance formed when chlorine combines with undesirable bather
contaminants, causing chlorine odor, cloudy water and irritation
to skin and eyes.
Chlorine
The most widely used bacteria-killing agent for water.
Chlorine level or residual
After spa water has been sanitized, the amount of chlorine left
over to kill new bacteria entering the spa.
pH
A measurement of the acidity or alkalinity of spa water. A neutral
reading of 7.4-7.6 is ideal to maximize chlorine effectiveness and
provide bather comfort.
Scale
Hard deposits that form on spa surfaces and equipment due to excessive
calcium in the water.
Shock Treatment
The addition of an oxidizer to destroy chloramines and other undesirable
compounds.
Stabilizer (Conditioner)
A compound added to protect chlorine residual from natural destruction
by sunlight.
