A couple of months ago, the display was indicating low salt, 2600. I cleaned the cell which had some deposits, and added 40 lbs of salt and it increased to 2800 as expected. I added another 40 lbs, but no change was indicated.
Everything worked fine until recently. The salt level kept decreasing until finally the generator shut itself off saying extremely low salt level. It indicated 2300 before it shut down. There has been no significant rain or overflow that I am aware of.
I checked the cell again and it had no visible deposits. I cleaned it anyway, but that made no difference. I am going to have the water tested (Leslie's), but from what I read on the forum, the tests can vary greatly. In the event the tests don't show a low salt level, is there something else I can check before shelling out $400-$500 for a new cell?
The cell is a T-Cell-15. It was installed with the pool in Sept 2010. I run the generator at 30% or less all year. Is there something I can be doing that would lessen the life span? Everyone else I see on the forum is getting over twice the life out of theirs.
