As my signature says, the pool was built in 2007 with a SWG and for quite some time it was a dream to keep the pool in perfect order. However, about three years ago (the system was about 5 years old), everything started going wrong. First, the cell died, and I about died when I found out what it would cost to replace it. The pool company that built the pool said it was defective and some sort of recall, and replaced it at no charge. However, this was the first of many future shocks. Six months later, my pool heater core developed a leak, and after 1000 of repair/service costs, Hayward finally replaced it at no charge. The cost of all the chemicals to run the Mineral Springs system has always been an issue for me, so I'm glad to find out that what I suspected all along is true - -- that I can use what you all call "solar salt" instead of buying overpriced bags from the manufacturer. Next thing to go bad was the circuit board in the Mineral Springs. I bought one and replaced it myself and everything was back online for about a year. Now suddenly the system is telling me that the minerals dropped overnight from 2800 to 1400. I didn't know whether to believe it or not considering the problems I've had. I switched to chlorine tablets, since the store said I could use them until I find a solution, but of course now I see why my pH has been dropping like a rock and I'm constantly adding pH increaser and from what I've read now I know why.
So, I guess my first step should be to get a good test kit and test the salt, to see if it really is as low as it says or if the cell has gone bad (again)?
