Question About Testing Water

[jeepgirl]

Does anyone know how long the ph and other testing liquids stay good? I have a old kit and I can't find any expiration date on it and so I am wondering if it would still be any good to test my water. Thanks!

I got one that over 5 yo. and I'll trust the more than a dip test.

If you are using the API liquid tests, they have lives stated of 3 years and 4 years for different tests. I keep using them if the results seem reasonable in my circumstances. The lot number on the bottle is really a date stamp. The one on my nitrate #1 chemical is 17A0407 which means it was bottled in April 2007.
