Adhesive sealent.

I'm putting together a 200gal tank and i want to use the strongest and best silicone adhesive that's available.
Can i get help on which kind i should use?

I always use momentive rtv 108 which is clear or 103 which is black.

Agreed, Momentive RTV is my favorite. GE SCS1200 is also a good choice.
