8. Possible causes of low chlorine or no chlorine
• Excelpool System switch in OFF position.
• Desired Level % adjustment setting is too low.
• Low stabilizer (Cyanuric Acid). Chlorine is being
produced but the pool water is unable to hold on to the
chlorine, due to low stabilizer.
• Filter pump switched off or filter pump time too short (8
hours for average size pools, more for large pools).
• Salt level too low (below 2500 ppm, Low Salt LED on).
• Salt level too high (high Salt LED on).
• Low pH. Low pH oxidizes chlorine quickly, making it
difficult to maintain desired
chlorine levels. Adjust pH levels to re-balance water.
• Warm pool water increases chlorine demand—increase
Desired Level % or filter run time.
• Cold water (below 50°F) can cause Excelpool System to
stop generating
• (Generating LED flashing).
• Excessive scaling on cell.
• High level of phosphates in pool water.
• Some yellow algae treatments will use chlorine at a very
high rate and deplete the residual free chlorine. Manually
shock the pool if indicated in the directions on the algae
treatment. It still may be a matter of days before the pool
returns to “normal” and chlorine tests will show the desired
1-3ppm free chlorine reading.
