How
to
use:
Measure
pool
pH,
temperature,
calcium
hardness,
and
total
alkalinity.
Use
the
chart
above
to
determine
Ti,
Ci,and
Ai
from
your
measurements.
Insert
values
of
pH,
Ti,
Ci
and
Ai
into
the
above
equation.
If
Si
equals
.2
or
more,
scaling
andstaining
may
occur.
If
Si
equals
-.2
or
less
corrosion
or
irritation
may
occur.
SALT LEVEL
Use
the
chart
below
to
determine
the
amount
of
salt
needs
to
be
added
to
reach
the
recommended
levels.
Use
the
equations
below
to
determine
the
size
of
your
pool.
