I never used this stuff before, but I'd like to bond 2 dry Marco rocks together and a shelf rock. If everything is dry and I wait the 24 hrs it says to cure, will a shelf rock, maybe 3 lbs, stay put?
That bad? This is for new tank, I used half a tube trying to get these rocks together and if they separate in a few months from a snail or something I'll be pissed!
