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.
TIA,

That was a big mistake. You should have found the right thing before
contaminating it with inferior stuff.
You could use methyl ethyl ketone, or acetone, but the better would be
"weld-on 3".
Do your best to remove the other junk that you put on there before
applying the correct application.

You can also use thicker weld-ons if you need it,
and you can also make your own thicker weld-on using
weld-on 3 and scrap acrylic.
