I have a couple of API test kits. Cal. ( if I'm reading the date correctly) 09-10. Kh= 07-09. I believe the dates are sept, 2010 and july,2009. I just bought these kits from lfs in Feb. Are they too old?

I've seen this question often. When reading this, I did another google search and found this (look at bottom half of page):
Saltwater Aquarium measuring devices
Odd though, look at the description of the Salifert Mag test procedure. I thought the Mg-3 was brought into the syringe until the STOPPER was at the 1 ml mark and that the air bubble was fine to be under the stopper. I thought the objective was to measure displacement of the Mg-3 during the drop into the vial. I have to re-read my instructions.
Then again, not sure how old this info is, the method may have changes since.
Which leads to a pet peeve.....web pages with no revision date...

from what i found with API test kits they last up to 12 months after stamped date .. but come to find out not always true .. they can be off as the months go on by a lil bit i would really start thinking about replacing them ..

I'm going by the lot number.(something like: 22kh0710) the 0710 being the manufactor date. There is really no seperate date stamp on the bottle or box. I opened both kits in Feb. Would they still be ok or should they be replaced. When buying new kits... How do they expect you to know the date of thier product if you have to open the box to get it??????
