Working with glass isn't too much of a problem for me. My wife and I 
have done some stained glass work so I have the basic tools.

You are correct, many plastics will take on moisture which is why I 
was concerned about using that.  The glass worried me due to getting 
good seals with silicone. Did you use an "Under water" rated 
silicone, or just any old silicone adhesive?  Did you apply the 
silicone on the outside of the tank or the inside?  Inside could be 
a bit of a problem reaching in, so I was thinking of doing it from 
the outside - just cut the pieces so there is overlap to work with.
