Expired products ok to use?

[Bacon505]

So i been out of the hobby and recently restart my system. I have some coral supplements that recently expired, it is safe to continue using or discard? Supplements such as microbacter7, aquaforest reef energy, aquaforest reef vitalizer. It expired recently within this year.

Bacteria and other items will degrade with time. While they may be safe they might not do anything. I would not use them. I would rater start with something I know is good. If things dont go right at least thats one part of the equation I wont have to guess at.
