siliconing rocks?

[parrotchute]

Is aquarium silicone okay to use for gluing frag rocks to other things? I'm having a helluva time gluing one rock to another; two-part putty isn't strong enough and superglue doesn't seem to be doing the trick either....

I've never tried it, but it's not going to hurt anything. I'm not sure it would stick very well though... Silicone doesn't seem to adhere to certain surfaces as well as others. It's worth a shot though! The only problem I can think of is that silicone has to cure -- dry -- for 24 hours. Good luck keeping your frags out of water for 24 hours.

If the rocks are dry, I believe that the silicone will work well. If they are wet, it wont stick at all.

hmm, nevermind then...any other suggestions?

How about two part putty and a rubber band?

I've seen some people use those little wooden dowels you get at craft stores. They drill a small hole in their frag rock and shove the dowel up in there. Then you can put the dowel into a rock in the tank (usually the tank's rocks are pre-drilled as well, so you have many holes ready to go).

Brilliant! I like those ideas!

Don't use wooden dowel rods,use plastic ones instead.

Another trick is to use superglue gel AND the two part epoxy. The superglue holds the epoxy in place while it cures. After it cures it will hold up strong like bull

I'll try that, great!

That is also the best method for attaching corals to IME...Especially big heavy LPS colonies.

like said before silicon doesnt work well when the surfaces are wet. I've never used this product but have been told it works. It's more for cementing LR together as the superglue gel is best for the frags etc.

Yeah I use superglue to attach corals all the time, but the two part epoxy never seems to stick that well.
