Hi. We just installed our new pool and this is the first time owing one. Our PB had been maintaining our water up until this past week. They gave us test strips and a brief overview of the chemicals. Up until this weekend, we had only been in briefly once or twice, so our auto cover has been closed most of the time. I received my test kit the other day and got the results below.
So, based on what I have read here, I added 1/2 gal Muratic Acid to bring my PH down a little, and I am in the process of adding CYA to get that up to around 70. After swimming all day yesterday, my FC fell to 0.5 today, which I am assuming is from the low CYA and bring exposed to the sun all day. I bumped my SWG up to 80% (it was at 30%). I plan on working to get the CYA up and the FC stabilized, first. Then working on bring my TA down using the aeration method. Then using some flocculant to bring down the CH (our water is very hard, so I am not sure draining and adding fresh would help much). I just wanted to make sure I am going about this right or if anyone else has any suggestions.
