I have a 72 Gal bow front tank and just replaced one side of the tank. How long should I wait before checking for leaks? mike s 2010-01-23 http://forum.aqua-fish.net/?topic=new-here#2 Hi there and welcome, the silicon will require 24 hours before it is fully cured, if you add water before then it could take days to cure properly Hope this helps. mickey 2010-01-25
