Since I'm over 8 (unless 2" of rain lowers pH significantly) I have a little wiggle room on the lower side.
How much CYA should I add at a time?

Very interesting -- thanks for the link. I had no idea they were doing that.
Keep in mind that Kem-Tek's product costs 35% less -- $17.99 vs $27.98 -- so if you buy ahead, you can save quite a bit.
Is a quarter cup of 99% CYA a reasonable place to start if there is none in 4500 gallons? pH8+?

CYA is about 2# / quart. 1 lb will add about 20 ppm to your pool.
So, no, that's not enough. Put about 2 cups in an old sock, and hang it in front of the return.

Why not pour it in the skimmer and let it sit in the sand filter til it disolves? I need to wait a week between doses don't I?

Most people have to backwash their pool frequently when they start it up -- and end up losing their CYA. If you're sure you want need to do so, go ahead.
Added 121 oz 8.25 bleach to the pool at sundown. Just checked cl. I'm getting 2 or a little more FC and 5 CC. My pH is as I suspected, probably astronomical. I added 4 drops of the red stuff instead of 5, so it should have shown a lower pH than actual. Still LOOKED like 8.2. I gave it another jug of bleach.
I guess the plan is go get the CYA tomorrow after I confirm my theory that FC will be zero and CC will be who knows where. Stick some in the pool to get the pH to a measurable point. If I understand correctly, the CYA actually inhibits the effectiveness of the chlorine so it is desirable to keep CYA low til the pool is stable overnight.

With which test kit are you testing?
