Goodmorning,
Ok so we drained and diluted our pool all night Fri. and Sat. morning.
I added some bleach Sat. even though we were still draining/diluting just to keep anything from blooming.
I had to go to pool store to get reagents, so I had them test water;
FCL=5.0+
TCL=5.0+
PH=7.6
ALK=90
CAL=160 (way off my #'s)
CYA=40 (way off my #'s)
TDS=1500
COPPER=0
Heres my #'s that I took about an hour later;(4:30p.m.)
FCL=9
TCL=9
PH=7.6
ALK=80
CAL=250
CYA=70
Here are my 9 pm #'s (i didn't add any more bleach yet, i wanted to see if it would hold at 9ppm.);
FCL=6
TCL=6
PH=7.6
ALK=80
CAL=210
CYA=60-70(this is a hard test for me, my eyes suck)
Ok so the chlorine did'nt hold so I added 3.7 gallons, then i retested chloine at 9:45, it was at least 20ppm, i think closer to 25, but thats with alot of dilution from shotglass method.
Now here are this morning test results;
FCL=20(AT LEAST)
TCL=20
PH=8
ALK=90
CAL=220
CYA=70(maybe 60, i suck at this test)

Now then from all I've read I should go by my results over the pool stores, so I say cya=70. My chlorine held all night. So now do I just need to add muratic acid to bring my Ph down? Should I shoot for 7.4?
And since my cl stayed all night am i done shocking? I have to leave today so I won't be able to test or add anything between 11am and 7 pm.
Thanks in advance for your help
Anna
