I've never heard of different types of silicone for different size tanks. People that I know that have built 100 and 200 gallon tanks just used the stuf from the hardware store.
There other grades of silicone to be sure, but they're not for consumer use and you're not likely to run into them. They vary in the time they take to skin or cure and are used by building contractors AFAIK.
