This is my first post to this forum. Amazing information here. Thanks to all. Wish I have found about this site / forum long ago.
Inground pool - pebble sheen - approx 10900 gallons rectangular pool.
I am having issues with my Clearwater Zodiac LM2-24 SWG unit. The output control button to increase the salt production does not seem to work. When this button is pressed, the LED's on the panel should go up. Mine is staying put on the first one and is lit amber in color. However when the super chlorinate button is pressed, all the led's about 5 of them go green and a separate super chlorinate led is also. Green. The Add Salt light - used to be on but it is no longer since I have added salt to bring up the salt level. My reading from the Aquatest Salt test strip shows 4070ppm. The manufacturer recommends 4000ppm.
I just assumed that the cell has gone bad (has been used 4 years) and replaced the cell. However the problem remains. Unable to get the "output chlorine" button to work and light up the LED's.
I also have FC problems (Duh) which I am also trying to fix. FC is about 1-2ppm and TA is about 150ppm. PH is about 7.6 - all using a generic test kit from Leslie's. I am also planning on getting TF100 - testkit very soon. Water is clear but I suspect some algae with brown spots at different locations on the pool.
Any insights to my problem is much appreciated. By the way a call to Zodiac tech support recommended that I replace the cell as they suspected that it is faulty. Now after spending 500bucks I am still stuck with the problem.
