Hey all I checked my chlorine level today and it was basically zero - my salt level is showing 2700 but my test strips are showing 3700. I have cleaned my cell. My check salt level is flashing all the time but my power and generating lights are green. I added shock because I don't want to lose the pool it is a Hayward Tcell 5. It is almost 5yrs old so I am thinking it is warm out my salt level shouldn't flash unless it drops below 2600ppm- I want to change to chlorine what is the best way? Just use floaters? I have a 27ft above ground pool about 16k gallons based on the calculator. All other levels are good.
