I went ahead and removed the silicone from the vertical seal in the corner. Also, I remove the silicone from both sides on the bottom. I figured there may be a runner somewhere on the bottom.

Well i know the only aqurium silicon i can find around here is only rated for 30 gal tanks. So if your sealing the bottom of your tank it might not be able to stand the water
Oh, I never thought of that. I got the silicone from Home Depot. Here's what it says on the back: Meets ASTM specification c 920, Class 25, Type S, Grade NS. Crap, never mind just found this: Limitations: 30 gallons or less.

One big thing to watch out for when using silicone is that the surfaces to be treated are "clean and dry". You really do need a perfectly clean surface to get the stuff to work at its best. As usual, it's an hour of prep work and 5 mins with the silicone tube, but get it right and you'll only need to do it once, so it's worth investing the extra bit of time on the prep work.
Now, that I know I need different silicone. Anyone have any tricks to completely remove all the silicone. I tried with a razor blade, it got most off. There still is a slight residue left. Is there any cleaner I can buy?

Finally, can someone recommend a store(b&m or internet) thats sells silicone rated for 55 gal tanks? Thanks for everyone help. I think I would have drove myself mad if I would have tried it again.
