    Time to replace the salt cell?

    My salt cell( SC-48) has had a low amps warning since I opened the pool around May 1 when it was reading 1.9 amps. I tested my water today (it's been two days since last test which was a 5 on chlorine) and chlorine had dropped to 1. I ran the test on the Autopilot and now it says the cell is at 1.4 amps.

    1. Is it officially time for a new salt cell?
    2. What's the normal amperage range for a new/working cell?
    3. Where does everyone get the best deal online for salt cells?
    All I know about my pool at this point:
    Size: 17,000 Gallons - Oval
    Type: Inground - Vinyl - Salt Water
    Filter: Sand
    Controller: Autopilot
    Pump: 1HP Waterway Mustang - Single Speed (MUSTS-110)
    Heater: Aquacal Heat Wave
    Robot: Barracuda G4

    The first thing to do is to examine the cell to see if has an calcium scaling (crusty white stuff) inside. If so it just needs to be cleaned. While you are looking, take a look at the corners of the cell plates and see if they are all even/square or if some of them are substantially worn. A clean cell that is several years old with worn cell plate corners is old and should be replaced.

    Normal amp readings are between 5 and 8, depending on the cell power setting.

    I ran some acid through it for about ten minutes and the level got back up to 1.9 amps but still way shy of 5-9 amps. Guess I'll be buying a new cell tonight. Any recommendations online for the best deal?
