I’ve been using all liquid chlorine for the past 2 months. Now I need to raise my CYA a bit. It is currently 30. Is this ok to use or is there a good recommendation? Also, will it throw anything else off that I need to be aware of? Really taking a long time for me to get the Alkalinity down (currently it is 120 ppm) Pool season will be over before I get that to where it should be
