Hi all - great forum.
I have recently been having issues with my pool, mainly it going green a day or two after shocking it. I'm in FL so the thing is always cranking around 60-70%. The reading on the Aqua Rite unit was recently showing low salt and flashing inspect cell. Cleaned the cell the usual way and noticed calcium build up on the grid that I couldn't get off. There's not a lot mind you and the corners are not worn in anyway. It's a Turbo Cell T-15 and I've had it about 7 years. I took it to Leslie's to test and it read FAILED on their test machine, but I kinda take what they say with a pinch of salt (pun intended) as I'm always suckered into paying for a bunch of expensive stuff from them I don't really need. Oh, the unit said salt level was 1800 and Leslie's test said it was 4100! (and I haven't really put a lot of salt in the pool lately). Chlorine was reading zero.
Would like to hear some opinions before I fork over $600-700 for a new one.
