TA is around 200

[keithk]

TA = 200
Ph = 7.8
FC= 0

Pool calculator isn't working, so I have no idea how much acid to put in for the TA. Can someone help me?

Yep, even tried in IE, doesn't work. The pH works, but not TA.

If your goal is to lower your TA, you do that by lowering your pH to about 7.2 and aerating your pool to increase pH back up to 7.8.
Then do it again, and again, until TA is where you want it.

It can take days to weeks to accomplish this. There are complete instructions in Pool School.

So, when you ask the Pool Calculator to figure the amount of MA to lower your pH from 7.8 to 7.2 w/TA 200, I get 25 ozs.
