Two Part Epoxy

[Tad]

Hello--
Well--my plan was to get the plastic ornaments out of my tank least they become death traps as my clown loaches are growing pretty fast. So--I made this nice 3 level rock formation--I am not very creative but I tried. I wanted this thing to be secure and not crush any fish.

So--I followed the advice of so many fish stores and used silicone aquarium sealant to glue the rocks together. I let this contraption sit out in open air for a couple of weeks. I then left it in my big bucket of water for at least another week. When I picked it up out of the bucket--most of the silicone gave away. Grumble grumble.

My dad was here at the time of my "disaster" and suggested using 2 part epoxy. He knows nothing about fish--except the ones that taste good (blech!). So--I searched LOL forums and saw a few posts mention 2 part epoxy--but none of them list specific brands that I can find.

I searched a few different stores and read so many products. I finally purchased Anchor-Tite Landscape & Plumbing. On the front of the package it reads--"use on: pvc, ...... aquariums, sinks, tubs, masonry, rocks, ...., ponds, ....." "works underwater, warm, cold, sea, or freshwater." But it also says, "NOT NSF approved - Do not use for drinking water applications." So--I called the manufacturer (Super Glue Company)--and customer service told me that they just don't do the testing that I would need to tell me if it was okay for fish tanks--so she would not recommend using it.

Does anyone have any idea what stuff to use to glue rocks together? My fish are as active as my kids--and I can tell you that they all give me gray hair--so I would feel much better if the rocks were securely glued rather than just wedged together. Can anyone tell me what ingredients to avoid?

Thanks for reading this!
