Thanks for all the help. The water looks great.
I'm now steady Ph - 7.2, cya - 40, alk - 90.
cl went 10 - 5.5 - 2.5 - 1.5 - 1.5 in the last 5 days with 0 fc.
The last 2 days I've added .75 gals and 1.5 gals to try and get the cl to 3.
Should I shock again, or keep increasing the dose to raise the cl to 3
