I have an Aquarite 900, with software rev 1.59 and the cell needs to be replaced. It currently has a TCell940. Looking at Amazon, the third-party parts are about a third of the price compared to Hayward original parts.

Salt cell prices gone through the roof

My cell is approaching 9 years old and the operating voltage is creeping up (constant current controller). I can see on really hot evenings when the mains voltage drops down around 225V the output drops down to 94-95% so I know the cell is going to need to be replaced later this year. Doing the...

I can answer any questions you might have. Just message met thru this platform. And continue to ask TFP members for advice. Don't rely on the pool store. Their advice is to buy chemicals or salt cells even if you don't need to.
