So for some reason my pool guy put a gallon of muriatic acid in my pool bc my pH was 8.0 and he was obviously trying to get it down. I wanted to get it down around 7.2-7.4 range but unfortunately it is now probably about the 6.8-7.0ish range when testing with my Taylor 2006 kit. My TA also dropped (of course) from 60 to 40. I asked him why he put so much MA and he said "bc I shocked the pool (15k gallons swg pool) with 2 bags of shock and it will raise the pH so I was added more than it called for of MA to counter this". Regardless, what's done is done. It's 3 days now and hasn't come up above 7.0 and the TA is still 40, so I was going to adjust it back myself. My plan is as followed:
1) Adjust TA first with Baking Soda (Sodium Bicarb) to bring it up to 60-70 range then...
2) Test pH to see where I stand, and adjust accordingly with Soda Ash (Sodium Carbonate) to bring up to 7.2-7.4 range
Does this sound right?
