I've never noticed before, but I was doing a water change last week, and when I opened my bottle of prime, it smelled horrible! Does it always smell bad? Or does it just go bad? Is it still safe to use?
I keep prime in my bathroom because I fill the water bucket up from there. Before someone told me prime stunk, I kept thinking the stink was because I needed to clean out the litter box. 3 months later I figured out it wasn't the litter box.
