Tank to Sump Ratio

[jords]

Thanks for the tip! I was planning on some good old silicone. Any actual difference between black or clear, other than cosmetics?
It's funny because my fiance says I shouldn't build my own tank. All because when we were at the LFS and said I was planning to, the worker said it's definitely not a good idea. Little does she not realize that the store only wanted to make a sale (that's why the store said they can custom make any tank I want).
