Hi I recently bought a 120 gallon aquarium and the guy threw in 40lbs of live rock however the liverock has been in a sealed container on his porch still in water but with no heater. It also has a clear jelly looking substance on it. Im setting tank up tomarrow do you all think it is still ok to put it in the setup tank I have a bunch of other live roxk and dont want to mix it if there could be dying rock or something that would raise nitrates
