Anyone Experienced with Aquarium Testing Kits?

[Sthronds]

I have a testing kit that I bought about 8 years ago and I don't see an expiration date. Does anyone know if those chemicals should be replaced or can I still use them?

They need to be replaced. Most of those things are only guaranteed good about a year. I wouldn't want to take a chance that I kill my fish because my kit was bad....

That's what I was thinking. Thank you!
