It took me about 20 mins total to get the trim off. Just started with a razor blade, and the rest comes off pretty easily when you yank on it. Cleaning up the silicone was pretty easy with just a razor blade as well.

^^ Every tank is different... it took me 45mins to get the trim off of a 10G because of how much bloody silicone was used... I could easily see a 180 that's over-siliconed taking awhile. :wink:

I think the trim mostly allows the builder a balance between time/cost to make the top look good and be safest for arms. I've taken a few off a long time ago and can't see how they add any structural strength being so think and flimsy.

I have a friend (seriously) who tried removing his trim on a much smaller tank and broke the glass. Yours is much thicker though so I think your only concern is time and effort which of course you have plenty of.

I say do it!
