Ok, I struggled this year keeping my pool water in check.
I am going to take a crack at learning how to use this poolmath.
The poolmath link says to first estimate your pool volume. My pool is 22x32x4.5 so about 24,500 gals.
Next I see the recommended levels for a vinyl bleach pool
Third, this is where I get confused, it says to enter your current test results in the NOW column. There is no NOW column on the POOLMATH page. I see GOAL and NOT SETUP? Am I missing something or are the directions incorrect?
NEVERMIND - I see at the bottom I have to specify the pool type and whatnot. NOw I see the columns with the goals.
Also, I have the TF100 water test kit and I found it difficult to get some of the readings, like the black dot test (CYA). I am willing to take my time again next spring I also had some older bleach and would add a gal and 2 days later have no FC, likely due to my missing CYA but I added a full container of conditioner.
