Not getting any bubbles or chlorine from new Circupool SJ40. When we start the pump we see a lot of bubbles and what looks like salt or sand running through the cell. Then after a minute the cell just looks clear, filled with water and the occasional small air bubbles.

Not sure what to look at first? The water values are fine. We know it could be the cell but would like to check options before exchanging it, as this will just happen again if it is not.

Been running the pump 24/7 and still need to add bleach. plenty of Salt 3700
Pump pressure is 20-22, not sure if that could be a factor?

What status does the display show for each parameter it can display? Are there any errors on the display?

Are you getting sand in the pool? The salt dissolves so you are not seeing salt.

Post all test results and how you got them, sorry but fine doesn't tell us anything.

Keep up with the bleach until this is figured out.
