    Ok, UNCLE! I give up

    I have a Hayward Swimpure system, SWG is 3 years old and kept spot less. The salt level in the pool was tested professionally at 3200. The issue; I purge the system per one of the posts on this site to clear the memory then re set the salt level to match the tested level. All is ok. I then check the salt level then next day and it is at 2500 or less which does effect the generation of chlorine, not very efficient. What is causing this? Is this an early signal that the SWG is on it's last leg or the board? Like I said "Uncle"!

    Welcome to TFP.

    How old is the cell?
    How long ago did you clean the cell?
    What do the cell baldes look like (worn edges, etc.)?
    What is the water temp?

    Normal cell life is usually 3 to 5 years so it might be time for a new one. Some Pool stores can test the cell for you and it may be a good idea to have that done.

    Will take it in to have it tested and let you know what happens.

    ok, the cell tested good on the Hayward Cell tester at the pool store. I set the salt level to 3400 last night and after I re installed the SWG it shows 2800, ok for the range but I'm sure it will continue to drop. ( Salt Level tested is 3200, water Temp is 71). Do I now suspect the main electrical unit is going bad? The reason I'm trying to be preventative is I live in Arizona, if the chlorine stops it only takes hours before algae sets in.

    A 400 ppm difference between the cell and the test is normal. If it continues to show more incorrectly then I'd give Hayward a call and see what they recommend.
