Throw away or keep and use?

Hello, I have some Red Sea reef nutrition an+ that I forgot about in my storage refrigerator. It’s been in there probably 9 months or so. It is opened but has been refrigerated. I can’t find and info on a use by date. Should I just toss it or is it safe to use? Opinions appreciated!

It is prob safe to use since it has been refrigerated. It will have lost some strength.
