Unfortunately, Ben doesn't seem to be in the kit business just now--it's been awhile since he's paid any attention to the forum and in fact has a very long list of people who have already bought kits and are waiting for them to be delivered. My suggestion is the Taylor K-2006, which is almost the same kit, and can be found at most pool stores or online.

In answer to your other question about vacation, if your FIL can come by and check on the pool say every 2-3 days, can he pour in a gallon of bleach? If you shock it before you leave with a CYA of 90 and he comes over, say, twice to add more bleach, then you should be fine. An alternative would be to get a new floater and cal-hypo tabs. THey don't add stabilizer. The newest ones really are not great because they dissolve too quickly and get kind of mushy, but they might do in a pinch.

I think personally I'd just shock it to the upper end of the recommended chlorine range, ask FIL to come by in about 4-5 days and pour in 2 gallons of bleach, and then take my chances. Beats worrying about it the whole time you're gone!
