I have a Hayward aquarite T-15 salt cell and when I opened the pool (~20k gallons) the cell was reading 1900. I put in 6 bags of salt and after about 24 hours it read 2800 (I've also seen this number drop depending the time of day) This seemed a little low to me as I was expecting more around 3200-3400. Rather then just buy more salt, I decided to buy the Taylor K-1766 kit to make sure my numbers were accurate. I just did the test (only used 10mL of water) and came up with 4400 PPM.
The salt cell was cleaned just prior to opening and the plates looked pretty good, but I know I'm at the upper age of cells. I've ran the cell at 45% for 12 hours during the day and 20% for 12 hours during the night for the last couple of years (not sure if this maintains life of the cell). I'm pretty sure I'm genearting chlorine since my level has stayed constant since I opened the pool a week ago.
Is it time for a new salt cell? Should I just wait until next year as long as I'm generating chlorine? Any reason to calibrate the Hayward to show the accurate number?
