Quick question!!

I am rearranging rock work this morning and have read several places that epoxy putty is good for adhering rocks together.

Is this true?

Will it put off chemicals in the water before curing?

Will it hurt my animals?

Also, I have seen where some use super glue for attaching frags.

Is super glue okay to use also?

I can feel my brain cells burning off while using it - does it bother the animals?

Thanks so much
Rhonda
