Basic Water Chemistry - Salt:
The AG unit is designed to produce chlorine on a daily basis. To monitor the system’s efficiency, the water
chemistry ranges, and schedule of periodic checks—per below—should be followed.
Excessively high chlorine levels can cause premature cell failure and corrosion damage to pool
fixtures and equipment.
Failure to heed the following may result in equipment
damage.
CAUTION !
REFERENCE SECTION
Always follow the instructions on the manufacturer's label whenever handling or using chemicals.
Failure to heed the following may result in equipment
damage.

EFFECT OF LOW/HIGH LEVELS CORRECTIVE ACTIONS
Low free chlorine: Not enough residual
chlorine to safely sanitize pool water. Low free chlorine: Check for combined
chlorine level and shock as necessary.
Increase purifier output to maintain a 1-3
ppm residual reading. Free
Chlorine
1 to 3 ppm Weekly
High free chlorine: Corrosive to metallic
fixtures in pool water. Can bleach
swimwear and hair. High free chlorine: Decrease purifier output.
Let chlorine dissipate normally until 1-3 ppm
is achieved. In extreme cases, pool water
can be diluted with fresh water or a chlorine
neutralizer added. (Diluting will reduce salt
and CYA. Check and adjust as needed.)
Low pH: (acidic) Equipment corrosion,
eye/skin irritation, plaster etching, rapid
chlorine consumption Low pH: Add sodium carbonate or soda ash pH 7.2 to 7.8
ppm
Weekly
High pH: (basic) Scale formation, cloudy
water, eye/skin irritation, poor chlorine
effectiveness High pH: Add muriatic acid or sodium
bisulfate.
Low TA: Eye irritation, pH "bounce",
stained/etched plaster and metal corrosion. Low TA: Add sodium bicarbonate. Total
Alkalinity
80 to 100
ppm
Monthly
High TA: Constant acid demand, difficulty
in maintaining pH, and contributes to scale
formation or cloudy water conditions. High TA: Add muriatic acid often, a little at a
time (may take a week or more to lower the
TA).
Low Salt: Below 2,500 ppm causes
premature cell failure and reduces chlorine
production Low Salt: Add salt according to digital
display on Pool Pilot unit or salt chart. Salt 3000 to 3500
ppm
Monthly
High Salt: Above 6,000 ppm can cause
corrosion of metallic fixtures and will taste
salty. Note: Cubby can safely operate
with salt levels up to 35,000. High Salt: If undesirably high, partially drain
and refill the pool with fresh water. (Diluting
will reduce CYA. Check and adjust as
needed.)
Low CH: Etching of plaster, equipment
corrosion Low CH: Add calcium chloride flakes. Calcium
Hardness
200 to 400
ppm
Monthly
High CH: Scale formation, cloudy water.
Rapid buildup of scale may exceed the
system's self-cleaning capability and
require manual cleaning of the SuperCell. High CH: Partially drain and refill pool with
fresh water to dilute. (Diluting will reduce
salt and CYA. Check and adjust as
needed.)
Cyanuric
Acid (CYA)
- Stabilizer
-
60 to 80 ppm
Outdoors
Low CYA: destruction of chlorine by the UV
rays from the sun. Low CYA: Add cyanuric acid(1 lb/5000
gallons increases CYA 25 ppm)
30 to 50 ppm
Indoors or
Colder
Climates
Monthly
High CYA: Requires more chlorine to
maintain proper sanitizer levels. Note:
CYA not needed for indoor or bromine
pools.CYA can be reduced to 30 - 50 ppm
for AG in colder climate regions. High CYA: Partially drain and refill pool with
fresh water to dilute. (Diluting will reduce
salt. Check and adjust as needed.)
