First of all I love TFP!! You guys have helped me a ton since i moved in a year ago and am totally new to pools.
So, this year the opening went fine cleaning the leaves out and vacuuming to start. Water looked good and i started to balance. TA was low, ph was good and the CYA was at 0, so I started balancing TA first.
I brought up the TA with baking soda, 13lbs worth and got up to a TA of 70. PH went up to 7.7. Next I added bleach to shock level thinking that this would be ok.
The next morning after adding the bleach i started seeing light brown staining on the steps, skimmer boxes, and return eyeballs. I left it for a few days and the stains have darkened. I tested it with vitamin c pills and it came right off. So now i am planning on doing the AA treatment.
Question: my test results are below and with a CYA of 0 what should i do first? AA treatment, bring up CYA, and then balance TA & PH or bring up CYA first?
Thanks and appreciate your help!!
