I have two questions for which I seek clarity:
1. Why is it that when the pool calculator calls for a certain number of ounces of bleach to get the FC to, say, 30, and I put that much bleach in the pool and then test several hours later, the FC isn't the amount is should be?
Then, I again put the numbers into the calculator, put in the recommended bleach, wait several hours, test and I still have a long way to go.
I don't get why the calculator states a certain amount of bleach will bring the FC 's to a certain level but it doesn't work.
My second question is:
2. Do I really have to go one drop at a time when testing FC for shock levels....?! I mean a potential 60 drops with a swish in between each single drop seems ridiculous. Today, I started going 5 drops and swish, until I began to get closer to the anticipated number and I could see the water beginning to go toward clear.
It that good enough?
