Silicone + Rocks
Alright, i've never used silicone to put rocks together, but i'm sure others have, which is why i'm asking it up.
Anyways, i have a pretty decently heavy rock.. maybe six pounds, and i really want it to stand up because it's an awesome looking rock. So.. my question is what kind of aquarium grade silicone should i use that is really strong, won't give out over time and won't let the rock break off, etc..
Also, any tips to sticking rocks together via silicone?
