I'm needing to glue a skimmer box together from my overflow as it got broken
before getting put into my tank. Anyone know what is the best stuff to use?
I've tried several different glues without success.

You need to use dedicated cement for acrylic available in plastics stores.
Use google.com to look up specific names and retailers in your area.
