Let's see. Our pool was installed 2.5 years ago. SWG wasn't calibrated properly. So I followed the instructions to field calibrate. Everything looked okay. It was set (and continues to be set) at 60%. Right now, we have no chlorine production. The only chlorine I have is because I shock it. If I let it go for more than a week and a half, my pool turns green. All the lights are on on the cell. Salt level reads "Good." Here are the numbers:
Size: 25,000 gal (16 x 36 oval; 3.5' shallow, 8.5' deep end)
Salt: 3590 ppm
CYA: 30-40 (this is part of strip, not it's own test. The color differences are hard to see)
I inspected the cell's insides and there doesn't seem to be any scale build-up (you can see that stuff, right?), nor any debris blocking anything. I try to increase the setting to a higher percentage, but nothing happens when I press the "more" button (or the "less" button for that matter. I also tried the "boost" mode, but nothing seems to register. When I press and hold down one button or the other, the lights start flashing and then go back to normal. I am sick of spending money on shock and would like the stupid thing to start working. Is weekly shocking just a part of life?
