    SWG reading Low Salt when I know that not to be the case

    It's a Hayward Goldline Aqua Logic AQL-PS-8 system with the T-Cell-15 cell.

    Question is: Does reading a lower salt level on the computer than what is actually in the pool indicative of a cell going bad or does it just die in one shot? I can still make Chlorine, but I had to raise the salt level significantly to let the cell "think" I am in the right range.

    The first thing to check is to make sure the cell is clean of scale.

    If it is clean of scale then there is a good chance the cell is starting to wear out if the salinity readout is significantly lower than the actual number.

    Thanks Ping. I forgot to mention. I did clean off in a diluted acid solution. It didn't help. I think it's time for a new cell.

    Leslie's usually have testers for Hayward cells if there is one by you.

    Good call. I had it tested and it failed. It doesn't say why it failed. The result is either a pass or a fail. No in between. New cell ordered (online company) and is on it's way. I got 6 full seasons with the original genuine T-Cell-15. I only got 4 from the after market replacement (CompuPool). Needless to say I spent a little more this time and got the genuine again. The CompuPool was a cool design because you can see through the cell and see the chlorine gas being produced. But if the life isn't as good, not worth it.
