Testing salt level


New member

Help! My CompuPool SWG says the salt level is 4200. I know that these are often badly
calibrated so I checked with Aquachek test strips. 5600!
As a tie breaker I tried Taylor K-1766 text kit. 2400!
I have checked each of these multiple times. How can there be such a discrepancy?
How do I reconcile this?
With SWG set to 50% capacity and running pump 12 hours/day chlorine is fairly
stable around 7.

Inground 16000 pool.
Free Chlorine 7
Combined chlorine 0
ph 7.6
TA 100
CH 260
CYA 60

I have had the same problems as you, and never came up with a solution. On my CompuPool, they are waiting on my salt to come down some and are going to walk me through recalibrating the SWG. You might talk to them yourself and see what they say.
