Due to my zipcode being very hard hit with COVID-19, 12% liquid chlorinator has been hard to come by temporarily. After opening, I saw that both my CYA and CH are below where I like them, so I ordered some granular trichlor and cal-hypo online and I am experimenting with alternating them (being VERY careful not to mix them ) until my CYA and CH come up to where I want them and hopefully by then, liquid Hypochlorite should be more available (as well as it being safer to shop in person). Is anyone else here doing the same thing this season? My pH usually drifts up anyway so I am getting the added bonus of the acidic Trichlor keeping it down a bit.
