Acrylic help needed

[bigsink]

This is my brine shrimp hatchery. Like a knucklehead, I dropped it and cracked. I was told that Weldon will not work with this. What epoxy can I use to put inside to seal up the crack? Obviously, must be invert safe. I cannot patch the outside. Patch must be low profile as well.

Try crazy glue or two part epoxy. Both should work.

Which 2 part? Same one used to mount corals?

Loctite 2 part from Home Depot will work fine...it's not a pressure situation.

Silicon doesn't really work on acrylic, Poly cast, Lexan, etc. Go with a two part epoxy.
