They do expire but normally those have a date on the bottom of the bottle? I've always been told if they're really old to shake the bottles really hard to break up anything that has settled?
These types of test kits are really unreliable anyways though and not very accurate.
Your tank shouldn't really ever show ammonia or nitrite anyways only nitrate if your tank is fully cycled

I know it never should, but they have never shown anything at all, ever

Yes they do and im surprised that the bottles dont have an exp date printed on them. I like api test kits for one reason,...theyre cheap and work ok if your just setting up a tank to see where your cycle is. I havent tested for ammonia or nitrite in a long time and mainly rely on the looks of my fish and corals to let me know if something is going wonky. I do test for the big 3 Ca/Alk/Mg and use a red sea kit for that. I hear salifert has great kits too. You could always bring a sample to a reputable lfs or a fellow hobbiest and im sure they would test it and compare results. Good luck and Happy Reefing.

I have that same kit, and I think mine are expired too. My PH has always showed good around 8.3, but today when I hooked up the Reef Angel and calibrated the probe, it showed 7.9.

Did you do the dual range calibration on your probe?
And yes test kits do expire.

Yes, calibrate with 7.0 fluid and then with 10.0 fluid
