Your Pool Water Maintenance Guide

Water Maintenance Tips - C-Pool Mineral Treatment

Water Readings

After a pool is up and running, and the water is clear, check water levels with a test kit.

An Alkalinity reading of 120 ppm should be maintained. BELOW 80ppm: turn filter system off and add baking soda to one corner of the deep end of the pool. After 15 minutes, turn the filter system back on. ABOVE 150ppm: turn off the filer system and add Muratic Acid to one corner of the deep end of the pool, then turn the filtering system back on.

Check pH and maintain between 7.2 to 7.6. If pH is lower than 6.8, leave the filter system running and sprinkle baking soda evenly over the pool surface. If pH is higher than 7.8, leave the filtering system running and add Muratic Acid by pouring it 6 inches above the water surface while walking around the pool.


Water Hardness

Most city water is usually high in water hardness. A reading of 160 to 220ppm is ideal. It is recommended not to add pool hardener (calcium) unless the reading is less than 100ppm. It is also better to have the water hardness on the low side rather than on the high side.


Chlorine Or Bromine

A reading of 1-3 ppm at all times is ideal. To achieve this reading, fill Chlorinator or Brominator and place on a low setting. If you do not use an automatic dispenser, place 1 chlorine puck in the skimmer basket at a time.


Shocking Pool Water

It is recommended to shock your pool water every week or two with liquid chlorine. The reason for shocking is to have a quick spike in your chlorine reading to destroy any bacteria that may have grown tolerant to regular everyday levels. It is recommended to shock between 5-7 ppm of liquid chlorine depending on pool size.

*Above Ground 2-3 Litres                                   

*Inground Pools 4-5 Litres                                  

*King Size (20x40) 7-10 Litres


C-POOL Readings

Under normal conditions, the proper initial treatment and weekly maintenance will be sufficient to guarantee that there is at least 0.5ppm of copper present in the water. If testing, use a Copper test kit. A reading of .5 ppm of Copper is ideal, make sure to test once a month. 



Don't add any stabilizer in spring, there will still be some from last season. Use Chlorine pucks that have stabilizer built into them. When the pool is first opened, an ideal reading is 0-40ppm. With the use of stabilized pucks, the reading will gradually increase to between 75 and 80ppm, which is ideal during the peak of the summer.
