Hi. As title states, I have a Hayward Aqua Rite with T15 cell SWG. The cell is original cell when was installed back in 2008. The AR circuit board was replaced in 2019. We opened the pool 2 weeks ago. A few days ago the water started to turn green. I checked display and said 2800 salt level which was the same of about 2 weeks ago. Didn't seem right so I did an instant reading. It went down to 1700 so I added salt. A day later it stated high salt so I did an instant reading again, showed high salt then it went back down to 1700. When I perform the instant reading, the readings show the correct levels for generating (amp and voltage). So I am trying to figure out if I have a bad cell, bad circuit board again or both. I have no lights indicating bad cell. Thank you.
