Does anyone know of an all purpose glue that can be submerged in water other than silicone? I need to glue river rocks to a peice of styrofoam for a waterfall efect for my vivarium project and I would need a lot of silicone and it wouldnt be cost effective. Would Gorilla Glue or Elmers Ulitmate glue be ok to use? I will be posting picture of my vivarium proect once everything is put together.

Thanks
Joe
 
AFAIK Gorilla glue is safe. Cyanoacrylate glues are safe, I use Loc-Tite gel superglue in my SW tanks all the time. The only thing I'm not sure of is whether either type of glue would react with polystyrene/styrofoam and release a toxin.
 
AFAIK hot glue should be fine as far as toxicity goes, but I don't think its going to hold weight long-term. It doesn't really bond that well to low porosity material.

I glued an awful lot of rocks together for about $7 or $8 using two tubes of Aquarium Silicone from Lowe's. I'd stick with the silicone… you don't have to buy it at the LFS.
 
I know this is a pretty dead bulletin but still. Could I just use normal hot glue to glue rocks, wood etc. together in a tank?
 
OK, can that idea. But what cheap adhesive could I use to stick rocks and maybe some driftwood together for caves?

Silicone... you can buy a tube from home Depot or Lowes for relatively cheap. Just make sure it 100% silicone, and dont put in your water until its entirely dry and no longer has a vinager smell.
 
Cheers guys
