Old premixed Reef Crystals

[PeterReefer]

Just wondering if anyone has an idea of how long premixed Reef Crystals are good for? I just found a 5 gallon bucket that I filled at my LFS about a month ago. Would anyone here use this water for a water change?

I'd use it. I keep water in my bins longer than that. Just test alk, salinity, etc before using

Just check the salinity in case there was evap.
