I'm a newbie to BBB but already a permanent believer. I'm almost at all my target levels for BBB, but am having problems with one last kink: getting a 0 CC reading (or <= .5) I've achieved a 60-80 ppm CYA, a lower (for the first time) TA level, and borates = 50. As far as learning how to maintain the absence of CC and the correct FC levels, I can't "try" that at all because I've never been able to get below 1.0ppm CC no matter how high I shock my pool. It has me scared that it will always be this hard to get CC back to 0 every time it rises above 1.0 or 1.5 again and it's necessary to shock.
I've been working on this "kink" in the process since May 3rd with some coaching from other BBB supporters. Each evening the past 23 days, I've tried to reach shock levels of 28 ppm by putting anywhere from 1-5 gallons of 12.5% bleach into the pool (based on the poolcalculator's results,) but my FC has never tested over 16.5...... until this weekend. Yesterday from 7 am until 10 pm, I stayed on it and put a total of 12 gallons in (2-3 at a time after each reading based on calculator) and I am currently at 26 ppm FC. But....I still have that 2.5-3.0 CC as well!!!
I'm reaching defeat. There are more hours my kids can't swim then when they can because of the constant shocking and higher FC levels (and because it was explained to me that CC levels => 1.5 can create irritations to the swimmer's eyes, etc.,) so I've been limiting the amount of time in the pool. Three weeks ago, I thought my pool would be ready by Memorial Day weekend if I stayed on it and kept at it; all this would be worth it because once we reached it the maintenance would be easier. Well, here we are, and my readings are still basically the same and we still can't swim.
Can anyone spend some time helping me? Thanks.
