READ
THE
DIRECTIONS
ON
THE
CONTAINER
FOR
CORRECT
CONCENTRATION
OF
THE
CHEMICAL.
TYPICAL
CONCENTRATION
LEVELS
1:20
to
1:60.
It
is
best
to
de
‐
lime
more
often
with
milder
acid
solutions
than
waiting
until
there
is
heavy
build
up
of
white
minerals,
then
trying
to
remove
the
build
up
with
very
strong
acid
concentrations.
Using
too
strong
of
an
acid
solution
or
running
it
for
very
long
periods
of
time
will
erode
the
metal
of
the
impeller
because
it
is
spinning
in
the
acid
solution.
