New fill - what's first? Total Alkalinity or Calcium Hardness? Water a bit cloudy.

Keep track of how much dichlor you've added and use that to figure the CYA level and, from the CYA level, look up the FC range from Ben's Best Guess Chart. You won't get a reading until CYA gets to 30ppm. You may need add dichlor several time a day until the CYA comes up.

Use Baking soda to raise TA. Use Calcium Chloride to raise CH.

Thanks, BigDave. I'll watch the chlorine and get going on the TA and CH. I was curious if one needed to be done before the other in case they inter played. I've read posts about bringing X up pushes Y down, etc. so was checking.

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.
