Am I understanding the process to lower the TA corretly? I must lower the ph to 7.0-7.2 with acid, then aerate to bring ph back up to desired level.
yes, that is the correct way, but would first want to know if your PH has been stable. Not every pool is exactly the same, and while 110 TA is considered "high", if your PH remains pretty stable, and the pool is "happy" at 110 TA, you could just leave it be. My pool tends to sit around 100 TA, and my PH remains in the low to mid 7's. I could lower my PH, then aerate to bring it up, and see if this has an effect on my TA, but if I keep doing this over and over and over, its really not needed as all my other numbers are my priority.
Pool math says to use Borax to lower ph
Pool Math says Borax to
RAISE PH. Muriatic Acid is used to lower PH.
Previous owners left Clorox Pool & Spa Ph down. Can I use that product?
I wouldn't, and you will find anyone here would say no as well. Clorox pool products are known to contain a lot of other junk, but the PH down is one of the worst. Just a pool store magic potion. the only thing you need to lower PH is muriatic acid.
If you embrace the TFP methods, even as a new pool boy, you will find it very easy to maintain a pool. You stay out of the pool stores where they sell junk that does nothing, or makes your pool worse, and spend little on chemicals that are usually pretty easy to track down. Chlorine and muriatic acid are probably the most you will need for now.
This is a great read for a new pool boy!
