pool chemistry
The InnoChlor Chlorinator automatically generates free chlorine from sodium chloride salt. This can be used to
sanitize swimming pools, spa pools or gray water recycling systems. After the chlorine kills algae or bacteria,
it reverts back into salt that will be electrolyzed into chlorine when it passes into the cell again. The salt will be
recycled indefinitely however rainwater and fresh water will eventually dilute the salt and more will need to be
added periodically.
CHEMICAL
IDEAL LEVELS
Salt
3000 to 4000 ppm
Free Chlorine
1.0 to 3.0 ppm
PH
7.2 to 7.6
Cyanuric Acid
60 to 80 ppm
Total Alkalinity
80 to 120 ppm
Calcium hardness
Max 300 ppm
Metals
0 ppm
Saturation Index
-0.2 to 0.2
Calculating Pool Volume
For square and rectangular pools
Volume = Length x Width x Average Depth x 1000 Liters.
For Oval, round and kidney shapes
Volume = Length x Width x Average Depth x 850 Liters.
Controlling Chlorine Levels
When first installing the equipment, check the chlorine level daily. Set the output to maximum and reduce the
running hours if the chlorine level exceeds 3ppm. Increase the running hours if the chlorine level is below 1ppm.
When the daily results are consistent, change the testing frequency to weekly. If the testing is consistent, then
longer test periods may be used.
Notes:
• A high pH will reduce the amount of free chlorine and require excessive running of the chlorinator and
pump. Correctly maintained pH will reduce electricity demand and prolong electrode life.
• Sunlight will destroy free chlorine. Cyanuric acid will protect the free chlorine from sunlight.
• Excessive organic material such as plant leaves and dirt will consume chlorine.
• A correct chemical balance and a clean pool will use less electricity and prolong the electrode life.
Calculating Salt
Only use swimming pool grade sodium chloride salt (NaCl). The innoChlor will automatically adjust the output to
suit the salt level in the water. An incorrect salt level will cause premature failure of the electrode.
Salt Quantity (kg) = Pool Volume (Liters) x Salt concentration (ppm)
1,000,000
Example: A 60,000 liter pool requiring 3000ppm salt will need 180 kg of salt added.
