Recommend an Epoxy for gluing sand to acrylic

I use plain old GE silicone, cheap and guaranteed reef safe. A thin layer will hold crushed coral and sand quite well and sticks to anything.

any GE Silicone?

like http://www.homedepot.ca/product/ge-s...-290-ml/941923 ????

if so this would be cheap, maybe better for what im doing since i can make it look lumpy

As far as I know, GE recently changed their formulas so all their I and II silicone that you can find at HD etc. contains mildew inhibitors. Everyone used to use GEI Window & Door without any issues; not the case anymore.

Your best be will be GE SCS1200, which you can usually find at Acklands-Grainger (or somewhere similar), or if you only need a small amount you can use the All-Glass stuff J&L sells. It is just rebranded GE/Dow Corning (or some other brand) for 3x the price, but it's easy to find and at least you'll know it's safe.
