Adjust one a little. Let it mix. Adjust the other a bit. Let it mix. And so on. The idea is to slowly approach your targets. The pool calculator says you'll need nearly 90 pounds of calcium chloride. Don't throw it all in at once. Just a little at a time. Don't put it in with baking soda. Too much calcium chloride at once or close to the baking soda and you can turn your pool into milk.

On second thought, work on the calcium first - a little at a time - I'll guess about 10 pounds at a time. Then on the TA. Use a box at a time of baking soda.
