HELP!!!

[CRUSHER]

Hello,
I re-sealed my 30 gallon... will be ready to use in 2 days.
I need a bit of helpful information, the plastic rim that fits on top that holds the glass, what should i re-attach it with... I don't think i should use silicone, but do need to figure out what to use that would have a stronger hold than silicone... any ideas? don't want to use anything that would be toxic to fish.

sislicone is fine.factory uses silicone to attach them. those rims aren't really structural you dont even need to put it back on.
