Frags - dumb question

[Coralgurl]

Thanks everyone. Will try some epoxy. I have a small chalice on a plug and I can't get it to stay anywhere. I attached all my frags on rock rubble and let them sit for a few minutes before I put in my tank, they are fine, just don't like the placement and would like to attach to the sides of some of my rock. Have to head to Rona for plumbing parts today so will see if there's anything appropriate there, getting in trouble for being at the fish stores too much...lol

Keep in mind epoxy is not glue and will not stick to rock. It's designed to be used to wedge a frag into a space and harden in place, physically binding the frag. It won't stick to flat surfaces, so make sure you've got a rough crevice or indentation to mount to.
Also, most (all?) putty you'll find at the hardware store typically has metal shavings in it, not approriate for reef use.

i make a tiny ball of the play-dough, put a dab of crazy glue on the frag, jam the ball into it and put another dab of glue on the other side of the ball. I mount my stuff to the rockwork and the glass too and it's never failed. The epoxy is a nice interface between the two surfaces since it forms to shape as you push the frag down. If I remember I also toothbrush the rock a bit before doing this.

I'm going to try what I have and see if I just have to hold in place for a bit for it to stay. If not, will look for the appropriate product noted and give that a go.
