Can anyone decode these exp. dates/lot numbers?

Red Sea Fresh Lab:

That third marking is definitely a rectangle, not a digit.

In response to your question, 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.

Thanks, Mgamer! That's some very useful info.

looks like you need new nitrate tests ;)

Boy, oh, boy -- no kidding! I got both kits with a used set-up, so chances are the Red Sea tests are just as old.

I ordered a API Master Test Kit last night. :)
