Epoxy or glue?

[IAShane]

What are your preferences with different epoxies? I'm looking to cement my rockwork.

I've bought some aquarium epoxy and it works well, but are there any epoxies at the hardware store that would be reef safe and cost less?

Experiences?

I just use the two little fishes epoxy and dollar store super glue gel. Using both together forms a very tight bond. I never used the hardware store epoxies because the one I have worked great for me.

Two part epoxy once cured are typically inert. Some are water clear, some amber color when cured. You can find different formulated epoxies such as knife grade (thick and stays in place) or more liquid (water thin) for covering large areas, and cure times as well. I would go for knife grade type for rock work.

Might want to avoid Devcon 5-minute, because it might have some non-reef-safe stuff. The 30-minute is fine, however.
