Should I toss this stuff?

[Rawsreef]

Recently bought a used 220G tank from a local dude who was getting out of the hobby.

He basically gave me his chest full of goodies. Some of which were additives and foods.

The dry food I feel I can still use even though I don’t know how old it is, am I correct?

This other stuff I’m not too sure about, was thinking I'm better off just tossing it? Or does this stuff not go bad?

The stuff on the counter (first pic) I set aside cause the expiration dates have passed.. everything else I presume is still good?

Certain things expire some don’t I would carefully check every bottle look for a date if not go online double check and if no one says it can expire then go for it. Personally if I had the money I would throw most of the stuff out

I’ve used expired goods in the past without issue but you also have to consider as in my case how long it’s been opened. If it has a weird smell or color- obviously not worth using
Most chemicals have a sticker similar to a price tag. That is the expiration date (eg: 11/22 or 11-22) = nov 2022

You can pour the Stability down the drain. That stuff doesn't work even when it's new.

Dry medications will be good long beyond their expiration date.
