KEY POOL WATER MEASUREMENTS KEY POOL WATER MEASUREMENTS
There are four essential measurements of a
pool’s “health”:
1. Chlorine Residual/Bromine:
}
Chlorine Residual - The amount of free chlorine
in pool water, measured on a ppm basis (parts
per million).
} Bromine - Similar to chlorine, it is used to
sanitize water and measured on a ppm basis.
2. pH - The balance of acidity versus alkalinity in
the water. This is measured on a scale from 0 to
14, with 0 being the most acidic, 7 being neutral
and 14 being the most alkaline.
3. Total Alkalinity - The amount of certain alkaline
buffering materials in the water, usually
measured on a ppm basis.
4. Acid Demand - Determines for you the amount
of acid to be added to the pool water to return it
to the proper pH level based on the size of your
pool.
These measurements are made with your
test kit. Prevent pool problems before they develop
by using your test kit regularly.
CHLORINE RESIDUAL
When chlorine is added to a pool, it immediately
goes to work to attack and kill bacteria, algae and
other foreign materials in the water. In the course
of destroying these organisms, the chlorine literally
gets “used up”. It is also dissipated by sunlight
and lost by water splash-out. The chlorine that
is left to protect the pool water against incoming
bacteria and algae is called the “chlorine residual”.
For proper disinfection, the free chlorine residual
should be maintained at 2.0 parts per million (ppm).
