Just Bought House With Pool -- Working On Water

[Andyman33]

I've been reading here for about 2 days now -- looking about how you are advising others to get the water straight and have made a few changes etc, but we are still with a cloudy pool (VERY) and I am hoping for some advice. First of all, the pool is 16k gallons inground fiberglass vinyl liner. It has a nature2 in addition to sand filter (although the nature2 is not active at this point). The pool was at an unoccupied house in Wisconsin and wasn't first opened until friday of 4th of july weekend...so we are definitely behind the 8-ball. I already have ordered the taylor 2006 testing kit but for now I have test strips to test free chlorine and hth's 6 way kit. When we got to the house, there was no chlorine in the system (not sure how long but I do know they used the pool for about a week from july 4-11 or so)...that is what I'm starting with.

Initially when tested ph 8, TC 0, TA 200, CYA 0. I have strips and FC was also zero on that.

I since have added acid trying to get the TA down as well as the pH, and also have added chlorine (both the tabs in my feeder and 4 bottles of shock (aka sodium hypochlorite 10%) and TA is now 180 ph 7.5, TC 4, CYA undetectable but the strips still show FC zero. SO....I have also been using poolcalculator.com and I also learned that unscented bleach was just as good but its only 6%...told me to add 330 mL's of 6% hypochlorite...which I have done. So now the question is this --- do I add CYA so that the chlorine stays around (it is like 96 degrees all this week)? Do I work on the TA? Do I give it 48 hours with this chlorine that I just put in? Or do I pump out a bunch and put in a bunch of "fresh"(our city softens the water for us, will that matter?)

Thanks for everything -- just want a CLEAR pool Can't even barely see the last step!!!

just checked the water...still with ZERO FC on the stick -- btw I tested it in a bucket and the strip definitely changes when chlorine is in there. Do I just put in more chlorine or do I need to wait until morning? Also should I only add chlorine at night? Should I add the CYA prior to any more chlorine? Or is best bet to just pump out a bunch of water and refill...thanks
