thinking of building a small refugium out of plexiglass. what do you use to glue this stuff together?
what would be the minimuim thickness required for a small unit.

thanks

how small is small? depending on the volume, you could get away with 3/16 but 1/4 would work better.if you use 3/16, go get some corner braces from plastic works on 132st/80 ave in surrey or some plastic store. they are basically corner pieces that you can glue into corners to reinforce the corners on thinner plastics.

something in the 12"l by 12" deep and 3-4 " thick.
sounds like those corners would be handy...if only i could get to the coast...

For glue use WeldOn 16 ... takes a while to set but stronger than hell and is a "conversion" cement capable of gluing PVC, ABS, Lexan, Acrylic and almost any other plastic. I've used it on Calcium Reactors, Fluidized bed filters and a few other reef projects with great success.

Methylene Chloride, then re-inforce with silicon.

For that height, use 1/4" at least. I like Weldon 3 or 4 and a thin bead of Weldon 16 afterwards.

I second Methylene Chloride. I built my DIY overflow and refugium out of it, with 1/4" acrylic. You just have to make sure the pieces are perfectly FLUSH. The solvent wicks into the crack and bonds them.
