As chem geek mentioned you do Not need to count the drops for the CYA test just mix the solution half water, 7ml, and half CYA reagent 7ml to =14 ml, per the markings on the plastic vial with lid, shake vial for 30 seconds, then add mixed solution to the small side of the testing tube with the dot on the bottom. Continue to add till the dot disappears completely, and compare that level with the numbers to the right of the tube.
If your CYA level is too high to do it normally, and you can not determine an exact reading, dilute the mixture as chem geek described above, so you can know exactly where that level is at so you can add chlorine accordingly.
Also with Your CYA being so high you will be testing it frequently at 1st and you will most likely run out of R-0013, so you will probably want to go ahead, and get some more of that ordered before you do run out of it.
TFTestkits.net carries a 2 pack with (2) 4 oz bottles, or an 8 oz bottle of the replacements of the R-0013. Those particular reagents are located at the bottom of page 1, after you click on the Taylor K-2006 refills tab. Other places also carry reagent refills too, but most are not nearly as reasonably priced.
I also agree as Beens said, using the 10ml sample instead of a 25 ml sample for your chlorine, and other levels will be a lot easier to calculate, and a lot cheaper due to using less reagents for testing.
The idea level for your CYA is 40-50 because otherwise you will go broke buying chlorine, and will still not be effectively treating your pool. The others will advice you more on that shortly, but the main thing right now is just to start getting that CYA level down as much, and as fast as possible (without Completely draining the pool),to try to beat a full algae outbreak.
Just keep reporting back on your numbers, and the pros roaming around this wonderful site, will be able to advise you on what to do next. Have a wonderful night and these guys, and gals around here will teach you how to get your pool in order, and be able to keep it that way.
