Best way to open a AG pool after the winter

OMGoodness. I have been up since 2:30 am central after 2-1/2 hours sleep (watched the Blackhawks win!) and had a brain freeze. You will need BAKING soda, NOT washing soda. I am so glad you responded right away!

And no, Borax is not washing soda. Different bird. Should you ever need it, look in the laundry aisle for 20 Mule Team Borax.

As for FC.... Since you are almost at shock level anyway, it seems to me that you may as well do the test now.

Your other levels are fine except for the TA. You could add a half box of regular baking soda at a time until that TA comes up. It's okay to do that at the same time.
