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.

16 or 17 year old salt system? You got MORE than your moneys worth either way! Do you have a Taylor K-1766 salt test to check it independently of the cell reading? Welcome to the forum.

15 years is a long time for a cell to last - I would have to assume it’s probably come to the end of its lifespan. Reading much lower salinity than actual is the first sign death.
Don’t add anymore salt
until you confirm your actual salt level with a k1766 test.
Others will be along soon to help you troubleshoot the other stuff

In the meantime you need to manually dose your pool daily with liquid chlorine & if you have visible algae or fail an
Overnight Chlorine Loss Test you should do the
SLAM Process.
You will need an accurate test kit to do this.

Thank you all for the quick replies. I just checked the display again and now it states 2500. I did a salt water test (I have a test kit, not strips). It came back at 4200! I then went back to the controller and cycled through the display to get the readings again. 2500, 65, 32.1, 0.00, 93P, -0, 88-0, r8.80. Turned off then back to auto. After the click, readings normalized to 2500, 65, 23.5, 5.41, 93P, -3400. Sounds like a bad cell?
