Okay so I just got a used tank. Pretty big. The previous owner resealed it and it hasn't leaked but he suggested that I reseal it again. I know lots of people on this site have resealed tanks on their own and I've read a few threads on how to do it.. So is it simple as removing the old silicone with a razor, re-apply new silicone thats safe for aquariums, let it dry for a couple days. Then test it with water?
