I just completed a SLAM a couple of weeks ago and am working on getting the water chemistry dialed in. I've been testing the salt with the strips from tftestkits and have constantly gotten a reading around 1700ppm. My Intex SWG says target level is 3000ppm and from what I can find it should throw a low salt code around 2500ppm? So are the strips inaccurate or is the SWG not too precise. In any case I'm thinking I should add salt? At 1700 to get to 3000 I should add 4-40lb bags, I'm thinking I'll start with 2 and retest?
