GE clear silicone from Homedepot or Lowes works fine
I have been using that for years without any issues

Silicone will not bond acrylic. You need to solvent weld the overflow box in.

WOW! I could not agree more with Uncleof6! (it had to happen, lol)

silicone would be a very poor choice for an acrylic to acrylic overflow box because although it might seem ok at first, it will, sooner or later (sooner), fail to seal. When it does fail, and your power goes out, the tank will drain to wherever the bottom of the overflow box is.

I've already got my solvent in the mail. Thanks for the tips. I thought I remembered hearing silicone wouldn't work so I wanted to confirm.
