I’ve been open for a week now and water temp with heater got up to 75-80. I usually just use liquid chlorine first couple of weeks because outside temps are in 70s but we had 2 mid 80s so kids wanted to hit the water. With that I decided to start up SWCG. Since FC already 5-6 with liquid I kept SWCG in 25% range for last 2 days.

Now the confusing thing is the difference between SWCG screen is more than the usually 300-400 between my liquid test. For instance screen keeps reading 3000-3100 while k-1766 with new reagent is reading 2400. Am I too far off? Should I just ignore panel and follow my tested result? SWG was inspected before my opening and completely clear as I usually am and it’s only 4 years old this year.

I tend to over think some of these things but just wanted to get some thoughts.

Salt Tests are +/- like 400, so you could be closer to 3000 than you think. You go by whatever makes your SWG work. I add less salt than pool math tells me and see if my SWG works.
 
I’ve always used that 400 rule but it’s a bit more this year so far. It’s on and pool is clean so I’m ok so far I think. I’ve been tempted to add one more bag to get me around 2800 by tester and also over 3300 on Aquarite panel 🤷‍♂️
