• Inspect cell for calcium build-up, manually clean
if necessary.
• Check for adequate stabilizer (cyanuric acid) levels.
• Increase CHLORINE OUTPUT setting.
• Increase chlorinator run time.
• Verify the pump/filtration system are clean and
operating properly.
• Test for salt concentration and add as needed.
