honestly i have this test kit, speed stir, a buncha bottes etc. i have no idea what to do or where to start. is there a writeup for that?
i dont know how to, and what to test first. i thought chlorine would be a single number but i guess its not? not sure how thats going to work. how does one test for multiple chlorine numbers? looking at chart the range is 3-13. thats quite a huge gap there. whats the number supposed to be for real?
