I recently switched to the BBB method. This was my first time to use gallon bleach.
I have the Taylor2006 kit and have been testing the water every day. I haven't had to add chlorine to the water for weeks because I have a solar blanket on the pool and everything has stayed pretty constant.
Over the weekend we had a crawfish boil at the house and so I took off the cover and left it off for two days. When I checked the fc it said 0. It was about 8 before the boil. I assumed it was uncovered and lost chlorine quickly. I used the pool caculator to get the chlorine back to 6 because my cya is 50. So it said to add 172 oz 8% bleach. I bought the bleach at SAMs. So I just added a jug. Well I checked my chlorine the next day and it was so high I quit counting the drops at 22 which would mean fc is 44 and it still had not turned clear.
I imagine I won't need to add chlorine for a long time now. I realize I added way to much bleach but I can't understand why the caculator told me to add that much. How do I know how much to add? Am I using the caculator wrong? Has anyone ever done that? Will that much chlorine hurt anything?
