    shocking, need help

    so i opened my pool sat 5/21 water was fairly clear added 3 bags of di chor, then later 4.5 gals of bleach next morning( sunday) 0 FC

    sunday added 3 more bags of di chlor and an hour later no reading.... water is very clear, at night with the pool light you can see a slight haze

    ok so today i stock up on bleach..... and do my first drop test an hour after adding the amount prescribed in the pool calculater ( 6.7 gal for a CYA reading of 70 at 0 chlorine) did my first test an hour after adding and reading was 15 FC and .5 CC ( suppposed to be 28)

    How am i going to be able to shock at a 28 FC if it cant hold the chlorine for even an hour? HELP

    The calculations are not making sense. Are you sure about the 6.7 gal? How many and what size jugs did you put in. What is the brand?

    As you add chlorine most of it is getting used up breaking down organic debris in the pool. Once all of the organic debris in the water is broken down it will be very easy to maintain the FC level. You just need to keep adding chlorine until you finally get there.
