To everyone on this forum. Thank you so much. And to anyone having doubts.. listen to these people. My pool was closed green and opened dark green(could not see walls or bottom). I read and understood the shock process and learned more on this site then in the last 7 years anywhere else. It was always a guessing game. After 2 1/2 weeks and 19 bottles of bleach and near the end after passing my overnight fc drop change I used 1 bottle of clarifier and the kids were in the pool.
Believe me there were many times I just wanted to go to the store with a sample... only because that's all I knew..
So here is my question. I now know that no or low FC causes algea and without throwing tablets in the pool how much can one expect to add bleach to the pool. My CYA is 25 and it seems like I go from FC-4 to FC-1 to 2 everyday. I am now super nervous and use the small test kit everyday for FC, which I think you guys suggest. I get full sun all day and I was wondering if I up my CYA willthe FC last longer because the chart calls for a higher dose or is it relative to a lower CYA and it is normal with this method to add bleach everyday. I read the full sun should have higher CYA. Does the CYA break down over the summer or is it pretty stable. Just not used to having to add something to the pool everyday.. but this method is cheaper easier and only takes 5 mins. The pool calculator usually calls for 1 quart and 2 cups of bleach or similar to that and just wondering if this is normal. Pool is clear and my wife was even impressed she doubted this process...
My kids thank you too..
