Hi all. First time poster, new pool owner. Bought an above ground pool this year. I wanted to follow everything I'd read on this site regarding water chemistry, significant other wanted me to follow pool store recommendations. Compromise was to do pool store recommendations initially, then I could do as I pleased afterward.
So, I ended up shocking the pool with dichlor during the initial chemical additions. I got pH and alkalinity where I want them (7.5 and 90) and have been testing daily, waiting for the FC to fall to where I need to add bleach. I've been testing for CYA also, expecting it to rise as the chlorine from the dichlor is used up, but it's always tested as non-existent. My FC tested at 2.5 today, so I will need to start adding chlorine and CYA soon.
My question is this: when I start adding bleach and CYA, do I need to somehow account for the fact that there is still some FC from the dichlor?
Thanks in advance.
Matt
