Just got an e-mail from Aq. Pharm. regarding their test kit shelf life... thought I would pass on the info.

"Each reagent bottle has a Lot # printed on the bottle. The last four digits are the month and year of manufacture. Example: Lot # 28A0102. This is a pH reagent manufactured in January of 2002. Pond Care Wide Range pH, Ammonia, High Range pH, Nitrate, Phosphate, Copper, Calcium and GH all last for three years. Nitrite and KH will last for four years. Freshwater pH(low range) and Pond Care Salt Level will last for five years. I would not trust these kits after they have expired."

Hope this is of use to someone else as well.

Cheers!
