Do Seachem additives expire? In particular I've got some Marine Buffer and Reef buffer that are old and I wanted to make sure they were still effective. I've also got a half bottle of Reef Complete that was given to me. Everything was given to me by someone who left the hobby so I really have no idea how old they are. It seems like the buffers would still be good but I thought I'd check just in case.

Unless it's something that reads it requires refrigeration I would prob use it.

Some manufacturers post expiration dates to increase product turnover.

Thanks for the input AndrewG! :thumbs:

Most of our products do not have an expiration date, so they will last indefinitely. The products you mentioned should be just fine to use.

I hope this helps! :D

I've got some seachem Marine Buffer and Reef Buffer (both crystals) that I used recently that was over 10 years old...

it worked perfectly....

Thanks for the info Rbredding! :up:
