Adjust TA first, right?

[jnorris]

I would add a lb. of baking soda at a time. Add it slowly to the skimmer while the pump is running. Don't need to predissolve it. Wait a few hours to let it circulate before retesting. I'd aim for an alk reading of 100. How high is your ph?

PH is 7.8 to 8.0ish.

I'm going to do as you said. You haven't steered me wrong so far!
