I have a 24,150 gallon in ground plaster salt water pool. 8 years old. I bought a t-9 cell two years ago and it's been a problem since. My salt readings are off and the chlorine generation is very low to nothing. I can't get any chlorine reading on the outlet. All the lights seem fine and the cell looks fine but I really have no choice but to buy another cell. Amazon lists two cells. I was recommended to go with a t-15 (on this forum). The price isn't much different so I guess I will even thought its for 40K gallon. Actually Amazon has a GLX turbo cell for $400 for 40k and $385 for 25K. Go figure. It fits Fits hayward goldline aqua rite pro salt chlorination and chemistry automation model aqr-pro
Also fits hayward goldline aqua plus salt chlorination and chemistry automation model pl-plus
40K-Gallons; 4000 hour plate
The other Amazon option doesn't say GLX or anything - it says it fits Goldline AQR - PRO, AQR, or AQR-X296, or Goldline controllers. There's a big difference in price $335 for 25K gal and $409 for 40K.
The only thing on my control box is : GL-939001D on the door it says: 5A0707-1029534 EP097
Any thoughts would be appreciated.
