I was running my intex saltwater system and it says I needed to add salt. Problem is it is a 16x48 Intex metal frame pool, and I already added 5 bags of salt. I cleaned the saltwater system with vinegar and it says salt level is good than 2 days later I get the low salt error. Been going on for about a week now. I am using city water.
Intex test strip that came with the system
Free Chlorine - tan color that is not on the chart
pH - 8.5
Alkalinity - ~200
not sure if the strips are correct, did two strips and same results
