Pool Still green after 20 gals of bleach...1st time post.

[Steve V]

Monday numbers

FC 14
cc .5
TC 14.5
ph 7.0
alk 125
CYA 50-60

by the best guess I need to run 5-10 ppm
I need to shock 20 ppm
using cya table 60-90 to be safe.
Do I raise it to shock table now to lower cc?Water is cloudy with light green tint. Filtered over nite and have no intentions to turn off.

Yes, because of the greenish tint--I would raise it to shock value now and keep it there until the pool clears, and until you can measure chlorine at sundown and again at sunup without losing any chlorine,.

Sundown 21ppm Sun up 16ppm added more bleach. Cya was 50 last nite...hope that's good enough.

50 is fine for CYA- and you don't need to test it again for awhile; save the reagents!
just keep it up with the chlorine, and watch your pH to ensure it stays 7.0-7.8 range; slightly high is ok at your chlorine levels, as the chlorine makes it read high...

[Steve V]

Will do. I will test ph and chlorine tonite and go from there. Also gonna try to vaccum the bottom for fine silt debris. Chlorine was 14 about 10am monday,added 1 gal bleach and it read 21 last nite...looks like it lost hardly any in sun. Lost some overnite though.

Tues PM 22ppm
Wed AM 21 ppm
That difference could be my readings. I added no bleach before I left for work.
Vaccumed last niite and it looks really good. No real debris in pool water almost clear. Gonna put stairs in it tonite. Maybe by the weekend it will be ready.
PH was 7.2 so I added a little borax to raise it.

What's your CC? that number should be <.5, and you should be done shocking!
Your pH will probably slowly rise as the water aerates- 7.2 is fine, as long as it doesn't drop.
I add about 3 cups acid every 2-3 weeks in mine, to keep pH below 7.8...
