It is rambling, my fault too.. I think it might be an IT thing, my apologies too. The meters they use seem to be conductivity meters of some sort, they rinse them out before testing.. it is an analog meter so they can't just subjectively decide on a number and anyone who can read a dial can read it, regardless of experience.Eco,
This thread seems to be rambling among several topics, I'll stick to the salt issue. Here's what I'd do if I were you. I'm not sure how many tests you've done are actually done with the K-1766 test kit but you need several in a row with this kit. Different tests methods are available they have a fairly wide range of accuracy even when performed with good technique. When different people with different levels of technique are used you introduce even more error. This introduces potentially a large range of accuracy error. The reason we prefer the K-1766 performed by you is it's the most accurate, reliable result you can get. So I would test with the K-1766 and post the result. If your result is outside the recommended range you should adjust necessary. Then do the test again each week and report it here. In the meantime it would be helpful to see a photo of your pool that shows all the skimmers and openings along the pool at the water line and a photo of the pool equipment.

I have tested salt one time which was when I first received the kit, which was after I turned off the SWG. I didn't think it was worth testing again because no other variables had changed. We did (last night) have a pretty good rain.
I posted photos in another thread of the equipment here Pump Failing
I can re-post those here as well if needed - with the additional ones for skimmers or to save server space I can just post the additional here. (which I will do anyway.. asap)
