I ordered some from Homegrown Hydroponics five? years ago and just ran
out. It never smelled bad or harmed my tanks. Something's fishy.

I ordered PMDD ingredients from a hydroponics website based in Canada

really bad lately. Smells a little like a dead fish. Anyone know if
this stuff spoils? Can I still use it or do I need to order a fresh
batch?

Thanks
