Hello all. This is my first year with a pool (10500 gallons) and I am stumped with my saltwater/chlorine levels. When I first started the pool up, I added 240lbs of salt per the instructions and the FC level held at about 1 ppm. Since then we have received a lot of rain and my SWG has shut off due to low salt. The FC was below .5 ppm and the salt level was around 1000 ppm. I added 120lbs of salt, waited a day and the SWG turned back on, the FC increased to about .5ppm but the salt level increased minimally. Is there something Im doing wrong? It shouldn't be requiring this much salt to allow the SWG to work to max efficiency, should it?
