    Default How long do chemicals last?

    I have some water test kits that are about four to five years old. I was wondering if I can still use these kits or not? I'm going to be starting up a new tank soon so I have no way of currently testing them. They have been stored in a cool basement on a shelf.

    To me, that's a very big difference between 1-3 years. Does it all depend on how they're stored or what? I throw any and all out after a year~especially API since it's so cheap
