Expiry dates

[hotashes]

Can I please have advice on if it's ok to use these items if and when needed although they do not have a date on them?

These ones below are actually out of date, can they be used if needed?

They all came with a 2nd hand tank package

Thanks, A

Some I wouldn't use even if new (Purple tech ), but the purely inorganic ones are fine regardless of date (Rowaphos, kalkwasser (forget the +2 lol), calcium and magnesium supplements, buffers, etc.

Ones with vitamins and amino acids in them may go bad or at least become less useful over time.

I can't read the ingredient lists. Look for vitamins or amino acids. If those are present, they may not be useful if old enough.

Thank you, as always.

You're welcome.

If there are some you are unsure of, just post the brand name and/or lists of ingredients.
