7.3.1
Chlorine Level.
Ideally, check the Chlorine level after the morning
operating period. The free chlorine residual level
should be somewhere between 1 and 3 parts per
million. Increase or decrease the output of the
Chlorinator to get the right residual chlorine level. It
may also be necessary to adjust the operating period
if you are running at minimum or maximum output.
7.3.2
Stabilizer (Cyanuric Acid)
Stabiliser (also referred to as Sunscreen or Cyanuric
Acid) AstralPool do not recommend the addition of
stabiliser in a pool controlled with an e-Q chlorinator
with chlorine probe fitted. If Dichlor or Trichlor is used
to supplement the chlorine production of the e-Q
chlorinator or Cyanuric Acid is added to the pool, the
set point of the chlorine (ORP) should be turned down.
Cyanuric Acid (CyA) is often recommended by or
added to swimming pools to make the available
chlorine last longer. It is often called stabiliser or
sunscreen. CyA bonds with chlorine ions which
prevents the chlorine from oxidizing bacteria and
other contaminants. This effectively reduces the
oxidization reduction potential (ORP) of the chlorine in
your pool.
CyA is used to extend the life of chlorine when the
chlorine is manually added in the form of a tablet,
granules or liquid and it is not monitored by a
measuring device. This reduces the quantity and cost
of chlorine used and maintains a residual chlorine in
the pool even though manual dosing may take place
every 2 or 3 days.
The AstralPool e-Q Chlorinator continually monitors
and produces chlorine to suit the pool’s chlorine
demand and costs very little to convert your pool
minerals into chlorine. AstralPool do not recommend
the use of CyA in conjunction with a Salt Chlorinator
that is suitably sized and incorporates a chlorine (ORP)
sensing device to produce chlorine. This includes
adding CyA to the pool or supplementing the
chlorinator with Dichlor or Trichlor, both of which have
CyA as an active constituent. In particular, CyA should
not be used in a covered pool, indoor pool or a spa
pool.
At most, CyA should be managed and kept within
a range of 10 to 20 ppm when used in conjunction
with the e-Q chlorinator installed with the Chlorine
Sensor. Ongoing use of Trichlor or Dichlor will
continue to raise the level of CyA causing a reduction
in the activity of the chlorine and may cause your e-Q
Chlorinator to continue to raise the chlorine levels to
excessive levels in order to reach the chlorine set point
(ORP).
If CyA is present in the pool water or Trichlor or Dichlor
is used to supplement the Chlorinator’s chlorine
production then the ORP set point should be adjusted
downwards until a chlorine level of between 2 and 5
ppm is achieved and maintained. Consult your pool
professional or certified Viron Installer to adjust your
Chlorine (ORP) set point.
As a guide, the following set point ORP levels can be
used as a starting point to achieve a consistent and
reasonable chlorine level.
Chlorine efficiency or activity is reduced even when
low levels of CyA is present.
