I wanted to piggy back off of this thread, and I think this already answers most of my questions. I basically have had the same issue. Pool was installed end of summer last year, but we had a leak and have had to have a new liner put in. This didn't finish until December. I told the PB not to add the salt back to the pool, but to just give me that bags and i would add in the spring. I will add those when the water temp starts to come up in preparation to run the SWG. I have been adding liquid chlorine to keep chlorine at 3ppm. I have been checking the PH and it has been between 7.0 and 7.5. Today it was 7.0. I have basically not added anything additional to the water other than chlorine. Is this okay? When should i start balancing my other parameters, in the spring when I add the salt? I have only been testing the FC, Total Chlorine, and PH, since I have not added anything else. Should i be testing the other parameters yet, or wait until I start adding in the stabilizer, alkalinity increaser / decreaser, and calcium? Thanks so much. I am going to update my signature to include my setup. .Its a 10,000 gallon pool, Vinyl Liner, 2.7 VSP, Jandy True Clear SWG, and a sand filter.
