TA at 120

[Tookiesmom]

I have a vinyl pool. My TA is 120. I tested this with a HTH 6 way kit until the better one arrives. I have been searching the forums to try and see what has been said about high TA. Also, testing my pH with the same kit, it stays between 7.2 to 7.5. So I'm not having any pH problems. I have seen posts saying TA doesn't matter for a vinyl pool. So am I ok here or no? I'm so confused.

TA only needs to be managed if your CH is also high and you are concerned about scaling. Otherwise you need to know what it is when you lower your pH as it affects how much acid is needed to lower the pH. Not something you need to worry about. You do want it over 50 to avoid any potential pH crashing.

My CH is non existent. Adding indicator drops to the sample barely changes it to a very light pink. So CH isn't high by any means.

Then you don’t have to worry about high TA. It means your pH will rise quicker, but you’ll add acid to lower it which will also lower the TA a bit. Over time it will drop unless more is added, say from high TA fill water.

Thank you. That's good to know.
