To everyone who makes this site, Thank you very much. I have been clueless on my first pool since we moved here.
Hello from Texas. I have been researching this site for a couple of weeks and pretty well guessed my main problems by reading pool school and how to clear a swamp before my test kit showed up.
40000 gallon in ground rectangular (mostly) with vinyl liner
2.5 hp Hayward pump
DE filter freshly serviced according to the DE article here
CYA 150 ish (off the scale of the Taylor k-2006 kit)
CH 375 ppm
pH 7.9 (may be a little higher, I'm a bit colorblind)
TA 125 ppm
CC 0 (assumed, couldn't get FC to show anything to start with)
So obviously after the 2.5 years of tablets used, my CYA is out of control, I gave up at the end of summer because chlorine didn't seem to be doing anything, now I know why. Right now, I'd just like to clear her up a bit to make the wife happy. Would it be okay to use up the granular chlorine I have left (about 25 lbs) just to get me to spring when I can start with the BBB method? Or does that have CYA also? I'd love to have my pool looking halfway decent for our annual Easter party just for looks. If I have to go through partial drain/refill it's not out of the question right now, but can I just limp along without causing myself a problem when it is time to open her up for swim season?
