This is my first time posting, but I've been on the site daily the past few weeks trying to learn all I can about caring for our pool. Thank you all for such great info.
A little background. We opened our pool about 3 weeks ago to a green swamp. I took a sample to two different pool stores before receiving my K-2006 test kit and one told me I had extremely high copper, the other told me I had extremely high ammonia. I wasn't sure who to believe (so I haven't done anything about those things), but we did know from our old test kit that our PH was below 6.8, the lowest our test would go. So, I got ready for the SLAM by first adding Borax (using pool math for amount). I ended up raising it too much and had to add muriatic acid to get it to 7.4 for the SLAM.
Our K-2006 arrived 12 days ago and we started the SLAM. Our CYA at that point was 40, so we used 16 as our shock level. We are only using Bleach. We kept it at this for a week, vacuuming and brushing sides daily. There was a lot of debris at bottom of the deep end. The water looked better each day for a bit and has turned blue, but we still couldn't/can't see the bottom. I decided to test CYA again at day 9 and got a reading of 55-60 which would be a shock level of 24. So, we have brought our FC to 24 for 3 full days now and have noticed minimal change.
Here's our numbers tonight:
My question is, are we on the right track and just need to continue what we are doing? Or could one of the pool stores be right and we need to deal with either ammonia or copper (or something else) before our pool will clear? Also, is it normal that CYA would change within a week, therefore our shock level changes? Its possible the CYA was an error, but I was confident I was doing it right the first time!
Thank you for any response, my kids are itching to swim with this hot weather we've been having in the Northwest!
