after a few days of tackling various things in the pool. the water is sparkling now .. thanks for all the help!
however, i'm trying to figure out the most economical way of managing the pool this summer.. last year, i used 6% bleach exclusively, and added some borax, washing soda and CYA over the summer... i think we were able to maintain FC pretty economically last year, except i remember CYA being kinda pricey. This year, i opened to really low CYA (less than 20) and low CH (around 120).
i purchased some HTH Dual-Action Tabs from BJs when I bought my liquid bleach and was just googling it and discovered that it's actually trichlor + copper + aluminum. not good, right? i don't want to be adding anything other than trichlor, right?
BJs also sells HTH Chlorinating Granules , which appears to be cal-hypo which would help me increase my CH and CYA, right?
Costco sells DuPont™ Pool Care Dual Purpose 3" Chlorinating Tablets which, based on google results, is 99% trichlor. I also think they sell Multifunctional Shock, which I believe is dichlor, some sort of clarifier and DuPont Oxone (whatever the heck that is)
are HTH Chlorinating Granules the way to go, considering i have low CYA and CH?
or should i just stick with liquid bleach and buy CYA and CH separately? I already added 18lbs of CalPlus (from Namco) but need to buy some more to bring it to the appropriate levels (CH is around 180 now)
thanks, i'm a penny pincher, but i also have a 3 month old and a 3 yr old at home now, so i should probably consider convenience too, which is why i bought the trichlor pucks.
