Ok the T 100 test kit came in today.
I shocked the pool (27' round AG) 2 days ago and was using test strips at the time.
I added way too much chlorine -4lbs shock and 4 gallons of 12% liquid chlorine.
The strips were not showing movement past 3% until I added the last 2 gallons of liquid chlorine.
I ended up with a bright pretty purple color on the strip that wasnt even close to the chart on the bottle.
These are the T 100 results:
free chlorine 19
combined chlorine 1
total chlorine 20
total Alk 200
calcium hardness 100
PH NA - forgot to test - 7.8 on strip test
So the chlorine is high and has stayed that way for 2 days.
Is there anything I should be doing?
I added 4 lbs of CYA.
I did plug these in to the calculator BTW.
