Which API tests expire?

[pneumaticbetta]

I have both saltwater master test kit and reef master test kit. Both are 5years old+. Which of these can I trust without worrying if they are expired?

Is there not an expiration date on the bottles?

looks on the bottles, if you don't find an expiration date just buy new kits. Its worth the $20/kit. Think if what can go bad without test kits.

And while you are replacing them, get better - I prefer Salifert myself.

yeah salifert is great. Also the red sea kits. The red sea reef foundation kit is good but you need to add some tests to it like nitrate, ammonia, pH, and kH. Also anything you dose you should test for.
