I changed over to pool school methods at start of year and am having my first perfect pool season in years!
So...it got cold in Michigan 3rd week of July so I started using new solar cover for 1st time in a couple seasons.
Following recommendations, I target FC=6 for CYA=55. CC all season has been 0.25 since first passing overnight test.
That has all meant pouring in about 75 ounces of 12% bleach daily...such that it became habitual.
When I put solar cover on, I kept up that routine for the course of a few days.
Then I checked chemicals and my chlorine had spiked high!
I didn't put chlorine in for few days until it got back down, then I did full check.
CYA=50 FC=4.5 and CC=O.0
First time all season CC=0!
Then daily checks, solar cover on every night and probably stays on 3 days per week.
In the last 10 days, I have used only 1.5 gallons of 12% bleach to maintain proper FC level in pool.
All other checks are perfect. Pool water is perfect. It all seems too good to be true.
I certainly don't want to jinx it, but is there a logical explanation for my extremely low chlorine usage?
