Granulatchlorine. But a straight answer would really help me. Is it first the chlorine and after the PH? Or viceversa?
I’m sorry but I do not know what the chemical composition of Granulatchlorine is. And without knowing what it is, or how much you're adding, it’s hard to give you a recommendation as to what order to add things in.
If you’re intent is to keep your chlorine level under 10ppm then I’d probably add the chlorine first, wait 20 minutes, retest your pH, and then determine if it still needs to be adjusted.
However, if your intent is to bring your chlorine level above 10ppm, then you won’t be able to accurately test pH after adding it. - in which case, you’d want to lower the pH first.
But if you lower your pH first to 7.2, and your shock contains CYA, then your pH might end up below 7 which is not good.
See why it’s hard to give you advice without complete info?
Post up a full set of test results, a picture of the label of the chemical your adding (or a link to it Online), and let us know what you’re trying to accomplish. Then we can give you direction that will help and not harm your pool.
