HELP!! Tank chipped

[GothFishKeeper]

I was just putting my Radion back on the tank after wiping the salt creep from under it when I heard a crack and its chipped at the top, do I use superglue, reef glue, or silicone to put this piece back in place? It doesn’t have to be the prettiest because it’s under where the light mount goes.

I would use a tiny bit of super glue, let it dry, and use a razor blade to scrape off any squeeze out (may be challenging to do so without removing the black paint/pattern)

Agree with glue, it's just cosmetic not structural damage.

I would get some fine wet/dry sandpaper and smooth over the sharp edges to prevent another crack from forming and not try to put the old piece back in place.
