Low salt error

[smithc84]

I just installed a Circupool RJ60+ for my 33k gallon vinyl pool. After adding salt, my Taylor kit reads 3200 ppm. The SWG reading bounces around a bit, but seems to settle out around 2500ppm. This results in a low salt error. I just opened the pool and I'm finishing a SLAM to clear it up. My numbers:
FC: 20
CC: 0.5
PH: 7.4
TA: 60
CH: 20
CYA: 50
Salt: 3200

My Hayward always read 600-800ppm lower than my Taylor test. Most important thing is to make the SWG happy. I would add more salt to make the SWG run, then retest with your kit and consider that your new baseline.

Does temperature matter much? My water is about 65° right now.

Temperature should not really affect the test although 65° is on the lower edge of where most swgs function
