My pool was built in April of this year and after 30 days, the PB poured in 7 bags of salt. I can't remember the initial salt levels, but by mid May, I could really taste the salt in the pool. My Screenlogic was reporting it at 4350 which was high so I had the PB come out and drain some of the water assuming they put in too much salt. They got the salt level down to 4000 and said that should be sufficient and as we use the pool more it will gradually go down due to splashout. Well here I am a month later and the salt level was up to 4200 so I went ahead and drained a little over 6 inches and filled it backup with the hose. I am currently maintaining 3800 which is much better, but my question is what could make it keep climbing? My specs are below and the only thing I put in the pool is chlorine and acid.
Note: I thought it might have been that my outside spigot which the auto-leveler is connected to was connected to my water softener, but realized that didn't make any sense because I used that same spigot to refill the pool so the salt would not have dropped, or am I missing something? I believe I read on here somewhere that muriatic acid could increase salinity, is that correct? I have been going through acid like water since initial startup. Any help/clarification would be appreciated, thanks!
