How long do you cure your silicone?
I am just finishing up building a big slate cave structure for my 55g tank's hardscape and used GE Silicone I to attach the pieces. Looking at the product's online information, it's supposed to cure in 12 hours, but I don't know if you cure longer for aquarium use? I looked through a bunch of posts on a variety of different forums and got pretty varied answers - usually anywhere from a day or two to a whole week.
How long do you wait for your silicone to cure? I don't mind waiting longer than necessary (I'd rather be safe than sorry), but a week seems pretty excessive, and this tank has already been pushed back for too long. So how long would you wait for it to cure?
