So, at a CYA of 45, you loose approximately 50% of your CL per day. The recommended minimum is 2.9 and goal is 4.6. Assuming you attain the 4.6 in the morning, you would be at 2.3 by evening and be below your minimum. To stay above the min. you would have to add CL more than 1 x per day. Does anyone do this manually? I don't have an auto anything.
It would be nice to not have to test and add CL every day. Is it true that at a CYA of 80, you can bring the pool to a FC of 9.1 and loose only 10% per day and still be above the minimum of a FC of 5.8...4 days later?!
I started out with a CYA of just over 50 and now tested it at just under 40 due to splashout and am thinking of making an adjustment.
