Safe to use expired Coral Revive?

[Tabasco1]

As title says... wondering if there is any danger in using expired Coral Revive? Would like to dip some corals before moving from QT to the display. Didn't think it had been QUITE that long since I used, but it expired in 2013...

Safe to use? Just maybe not as effective?

2013??
I wouldn’t use it.
Why not keep a few days longer in QT and drop by a LFS to get a new bottle.

If anything it won’t be as effective, if the bottle has never been opened then it might just be just as strong as a new one.

It might be ok to use but is it worth the risk? A new bottle is not to expensive versus what a coral might cost you. IMO, if it has an expiration date then it can go bad.

Thanks! It is opened. I don't have a local fish store. Closest is 2hrs away. So I'll need to order through mail. Just had free time today to hit everything.

Maybe you can use some bayer as dip?
