Hi andy, and welcome back!!

Glad the pool is up and running, hope you're getting a chance to enjoy it. As far as the TA goes, if the TA of your fill water is 200, and your pool isn't having any problems (i.e. your pH is stable), I wouldn't bother to lower it, because it'll be an endless fight-- every time you have to top off with fresh water, you'll be raising the TA again. However, if your fill water is lower in TA, then it wouldn't hurt to go ahead and drop it some.

Janet
