Two months of Pool testing results on a new pool...

I still say increase your CYA some. Also, don't test CYA daily. There is no need to do so and it just wastes reagents. As a matter of fact, the only two you need to test daily are pH and chlorine. Testing TA and CH once every couple of weeks is fine unless you use Cal-hypo or if you notice your pH bouncing around. Test the CYA every week or so until you get it where you want it then probably once or twice more per summer is plenty. (Unless you are using trichlor or dichlor. In that case, you'll want to monitor it weekly but not daily.)

You need to make sure that your chlorine level stays within the range in this chart based on your CYA level. If you drop too low, you're risking an algae bloom. http://pool9.net/cl-cya/

If you use the 10mL water sample instead of the 25mL one, then you will make your chlorine testing reagents last longer. You will multiply the drop count by 0.5 instead of 0.2.

Thanks for this information. My intention was only to test daily for a few weeks to determine what my pool is doing then back off to a more reasonable testing schedule as you suggest. Right about CYA testing and I was just testing this during the period of time where I am still making adjustments and I wanted to see what that value did too (it seems to have dropped a bit from May reading and not sure why). I have almost developed a periodic schedule for everything but I am not there yet. Another week should do for me.

I am still interested in my comments on my high Calcium Chloride. Any feedback here?

My chlorine additions need to be adjusted as you indicated. I am working on that.

I am adding Sodium Bicarb today to get the Total Alkalinity up to 90. Will check to see what that does to acid and adjust that tomorrow.
