Glue For Tank Ornaments ?

[Faythee]

I ordered 25 lbs. of slate and would like to make some ledges/caves and glue rocks together. What is safe and works best ?
Thanks

Try some silicone. It's used for holding the tanks together, so it would have no problems inside of your tank.

Cyanoacrylic is good, sets in seconds and totally safe. Silicon(e?) is also totally safe but it takes 3 days to cure.
