Is your kit also going to be delivered today? Do you have any kind of kit? If not, go ahead and pick up a cheap OTO/Phenol Red kit from Walmart (yellow and red drops). You cn use it in the interim until the good kit arrives. It won't test everything like the good kit will, but it will test pH and chlorine which is fine for now.

If the pH still reads above 8.0, go ahead and add a little muriatic acid (maybe a pint) slowly in front of a return jet once you get the pump running. After a couple hours, retest pH and add more acid if needed until you get the pH between 7.2-7.8. Muriatic acid is nasty stuff. Wear gloves, glasses, stay upwind of fumes, pour with the bottle very close to the surface of the water so it won't splash. With new plaster, you'll have to repeat this process frequently from time to time as newly plastered pools tend to have high pH.

You can also go ahead and add the CYA once your pump is up and running. Pour it slowly into the skimmer and then run the pump 24/7 for at least the next 4 to 5 days. Don't run the CYA test before then or else you'll just be wasting your reagents. It is slow dissolving and won't register on your test for about a week or so.

(BTW -- even with the Taylor K-2006, it will still be handy to have the little OTO kit for quick daily checks of chlorine and pH when you don't need to test everything. I of course have a good kit, but use my OTO kit frequently.)
