Corrosion, Pool Liner, Creasing or Discolouration
Possible causes
Is your equipment rusted? Is there discolouration on your pool liner and equipment? Is your pool liner creasing? Four factors can be related to these problems:
- Low pH
- Low total alkalinity
- Low calcium hardness
- Sanitizer level higher than 3 ppm
Suggested solutions
- Low pH: Adjust pH to 7.2 - 7.8. Increase pH using pH+.
- Low total alkalinity: Adjust total alkalinity to 80 - 120 ppm. Increase alkalinity using Alkalinity Control.
- Low calcium hardness: Adjust calcium hardness to 200 - 300 ppm. Increase calcium hardness using Calcium Plus.
- Sanitizer level higher than 3 ppm: Adjust sanitizer level to 1 - 3 ppm.
Preventive maintenance
- Low pH: Maintain pH at 7.2 - 7.8.
- Low total alkalinity: Maintain total alkalinity at 80 - 120 ppm.
- Low calcium hardness: Maintain calcium hardness at 200 - 300 ppm.
- Sanitizer level higher than 3 ppm: Maintain sanitizer level at 1 - 3 ppm.
* In order to maintain clear and sparkling water during the swimming season, make sure to have your pool water analyzed regularly by your specialized retailer to adjust and maintain the following parameters: total alkalinity, calcium hardness and stabilizer. Ideally, the week following the opening of your pool, in early June and late July.
