Is my cell dying?

[JimK]

UPDATE:

My cell seems to be having no trouble maintaining CL, so apparently it hasn't given out yet. The only mystery left is why last year the controller's salt reading was the same as my test strips, but this year the controller is reading about 300ppm lower than the strips.

Maybe it's time to try a taylor k-1766 drop based salt test kit? My local pool store actually carries those.

Thanks for the suggestion.

I looked into that before and decided to go with the AquaCheck Salt Strips that were recommended here. I was told the strips do a good job (they seem to do fine).

I'll take a look at the Taylor kit again.

I'm wondering if the 300 ppm is simply the normal range of error. I think I remember years ago being told by the pool store that installed our system (I was having them test salt back then; they were using the Taylor kits) that it was normal to see a variation of 200 ppm or 300 ppm.

I found an old post somewhere else made by waste that said the moa was 500 on this test (even with the 1766). I think you're probably just fine

Great info. Thanks!

Test strip are fine IF they are fresh but they do seem to go bad quickly.

Test strip are fine ...

Meaning the salt test strips (and borate test strips). In case someone reads this out of context.
