Is this a good price

Doggie, don't worry about asking the ?s - that's why were here. (BTW - congrats on your newfound seniority!)

You need the powder and the 2 liquids for the cl tests, I believe that #2 and #3 are the same reagents whether you use the powder or the liquid for #1 (the liquid only measures up to 5ppm TC, the powder can go to 50.

The cya I saw on their site was # 18563 which shows the mixing bottle, 2 bottles of the test reagent (they are both the same - you only get ~3 tests per .75 oz bottle, so they give you 2) and what looks to be the instructions (the square packet) and the test chamber.

If you want to know what other back-up reagents to get I'd say a large (2 oz) bottle of R-0010 Calcium buffer (CH test reagent #1) - the cal test takes 25 drops of this per test and R-0012 Hardness reagent (CH test #3) (1 drop = 10 ppm, so if you have high calcium, you can go through it quickly if you test cal weekly - which you probably don't need to do)
A back-up bottle of R-0009 Alkalinity reagent would probably be advised as well (again 1 drop = 10 ppm, so with an alk of 100, you'll use 10 drops/week)
If you want to get more of the cya reagent, it won't hurt- as I said you only get 3 tests per bottle and though you only need to test it a couple of times a summer (after you get the level where you want it) but as I said above - you kan keep the reagents in the fridge and might as well get it all at once as long as you're already paying shipping.

I hope that this is a little clearer than the website
