You use a razor blade to cut the old silicone and pry off the old trim. You can find videos on YouTube to help you out, then silicone the new one on. Is the tank still cycling or finished? You could just put your filter media, fish, and some tank water in a bucket while you work on the tank. As long as the media stays wet you're in the clear. I wouldn't lower the water level, just looks bad and there's still a risk of the tank starting to leak.
