Hayward AquaRite 900 Is Running but Chlorine Is Low or Zero: Whats the Cause?
Even if the display shows a normal salt level and the Generating light is on, you still need to test chlorine, because the amount produced may not meet your pools demand.

Salt Level
The number 3200 shown here is an example salt level of 3,200 ppm.
Free Chlorine

Start With the Unit Settings
The manual gives an example of about 8 hours of pump time for an average-size pool, but this must be adjusted for pool size, output capacity and chlorine demand. It is not a fixed time for every pool.
Check the Salt Level and Cell Condition
These can reduce or stop chlorine production. Look at the warning lights together with actual water test results.
Check the Waters Chlorine Demand
The manual lists other causes to check:
Adjust the % output and pump time, check water balance and retest chlorine. If a chlorine shock is needed, follow the chemical label and your pool caretakers advice.
Test water quality before using the pool, especially when chlorine readings are low or zero.
