Got given a bunch of supplements.

[Nor'easter reefer]

My buddy shut down his tank and gave me some random supplements. Some look to be quite old. My questions are as follows:

Which of these are most likely to be shelf stable for long periods of time?

Which of these is even worth keeping?

Check the dates on them; some of them could be out of date, and you don't want to use those in your tank.

Even if they are expired by date there is nothing in them that would cause any issues besides being slightly less potent.

I would not use Prime, except for chlorine

The Kent magnesium is fine

The Reef Advdntage calcium is fine.

I’m not sure what is in sea buffer but I would not use it based on the description without knowing more

I would not use old calibration solutions of any sort, such as the Accurasea.

The Kent super buffer is fine

Seachem Reef Builder is fine

I would not use old Reef plus (vitamins and amino acids)

The GFO is likely ok and the two magnesium products in the last pic are fine
