    So I am tinkering with the CSI calc and even if i put 200 CH in the CSI calc it drops from -0.12 to -0.29 with those #s I am very confused. The only things i can do to get the CSA to plus 0.5 are to raise the pH, Raise the alk and Raise the CH with pH having the most dramatic effect and being...

    So just for reference. I added chlorine this morning to 3 ppm. with the floater. I just checked and the 10 ml chlorine test is barely pink so a small fraction of a ppm left even with the floater. Do I add chlorine 2 3 times a day or just once?? my pH was 7.4 and alk was 80+ at the same time.

    @PoolStored @ajw22 Standing down on the CH increase. I read minimum 200 and read that as free to go to the ideal target range. My CSI is 0.07. Regarding tabs, I guess what I am asking is, is it harmful? Its easy enough to measure the Cya and I know its about 6 ppm per tab. My plan...

    @PoolStored Ok, so my reading comprehension may be suspect... I guess my confusion now is about the chlorine. On day 3 it says add chlorine to 1.5 to 3 FC, but thereafter says nothing about chlorine until the section on After 28 days.

    @PoolStored So far so good on day 2 following NPC program to a T + Jacks Magic Blue. On the NPC instructions. Day 4-7 says repeat Day 2 step 2 to adjust calcium hardness, which makes no sense to me. Should this be Day 3 step 2 to add the liquid chlorine? Is this a typo? On brushing i am...

    @PoolStored With the Jacks Magic Blue Stuff. Do I need the test kit for the maintenance dose or is it ok to just ball park with the estimate from the side of the bottle.
