I have an Intex Easy Set 18' x 48" (5455 gal.) We just bought a SWG to add to the pool. We ran the SWG for the first time yesterday. I got some salt water test strips and the reading shows 3470ppm.(i guess we don't need to run it as long as the book says). The only test strips I have are 3-way that came with the SWG. They show a reading of FC-3ppm,pH-6.8,and Total Alkalinity-80ppm. Could someone please tell me what I need to add to my pool? I am new at all of this.Thanks.
