Thank's for the info. I really appreciate it. I will be servicing these pools this week and I'll be cleaning the cells to get rid of scale build up. I did a visual inspection on these units and did not see any buildup. It may be there, just cant see it when wet. Again, I thank you and the others for the support. I will post results later this week.

OK, that answers that. I had the suspicion but no foundation. Thanks for the info and I think I'll make the investment in a digital meter. In the meantime, the cell's get cleaned again and start over. As I mentioned, out of 15 salt systems, all demonstrating similar characteristics, only two are having this "problem." I just thought it was kinda weird. Thanks again, I will post results after cleaning.

To get the result, you need to look from the top of the tube into the solution. Slowly bring the piston up to the surface until you can see the black dot. The reading is then viewed from the markings on the slide. The result is the corresponding number at the water line.

Yes. I've been using strips that are fresh. Dont have access to any other test device and dont trust the readout on the controller. (seen too many out of calibration....) Thanks for the input. I'll try cleaning the cell again, see what happens. Is my other question valid? Can I raise the salt level simply adding chlorine?

If the strips are testing high and the cells are reading low I would suggest cleaning the cell with acid. I suspect that they had scale buildup during the winter.

Howdy, I maintain numerous salt pools in the Orange County California area and am having difficulty with a couple of pools. During the winter the generators stopped producing Cl because of low water temp. This forced weekly application of from 1 to 2 gallons of chlorine to maintain clarity. Now that summer is here, 2 of these pools' salt levels have gone through the roof! One pool stays at 4200ppm, the other is around 4410. The system reports salt too low and the owners want to add salt.... nooooo! Both systems are GoldLine AquaRite. One has the control box, the other is integrated to the control panel. I am using salt test strips and have found them to be somewhat unreliable (ie; weekly test results vary from the same bottle of strips!) My questions are: Is this normal? The cell's have been cleaned and checked. Does adding liquid chlorine, 12.5%, cause the salt level to rise? Is it your opinion to drain adequate amount of water and refill? Thats it....thanks
