Why is the chlorine level low in my Waterco Water Filtration System?
- M
  Marilyn LewisAug 5, 2025
  If your Waterco Water Filtration System shows a low chlorine level in the pool, several factors could be at play. First, ensure that the operating time is sufficient; if it's too short, increase it. Next, check the production control setting and increase it if it's set too low. Also, verify the salt level and add the required amount if it's low. Finally, incorrect pool chemistry can also cause this issue, so have your water tested.
