I'm using the quick guide for my Intex Easy Set. I followed the guide, including purchasing the two way test kit. I just realized that the two way kit that the guide said I would need doesn't cover CYA. I guess I'm a bit confused why the guide recommends a two way kit (Chlorine and pH) because that doesn't cover CYA. Is CYA pretty stable and just not that important to test when starting the year fresh? Or did I make a mistake buying a kit that doesn't test for it? How vital is the test for the CYA numbers?
Thanks.
Thanks.
