This is a great forum. I have an Intellichlor I-40 on a 24000 gal pool. This is my issue. The green ligh that should be on for the cell is off. The salt cell is red for "low salt" My salt is 4200ppm. I tested it at the pool store. My TA is in the 160 range. It was around 170 before I added half gal of acid Friday. Then last night I added another gal. Have not checked today. When I add acid to bring the pH down the green light on the cell will come own for a few hours and the green "good salt" light comes on. Then overnite it all goes back to "low salt" and the green cell light goes off again. I have a waterfall, no spa, that runs about 4-5 hours a day. Could the high TA be causing the SWG to shut down. I recently shocked the pool with two lbs of the pool shock from lowes to keep my chlorine up. These numbers are approximate.
FC around 1.6
CYA was 16 and I added 15 lbs yesterday. Have no way to check accept at pool store.
calcium hardness was 224. I added 17 more lbs last night.
no Borates, though I really want them after reading this forum.
We have also just had a heavy rain last night and this morning.
Anyway thanks for any help I can get as to why my SWG is acting funny. Oh the pool is almost two years old. Plaster.
