I have a 125 gal oceanic tank thats a little over a year old. In the last couple of weeks i have noticed a small leak in the upper corner. At first if i didnt fill the tank to the very top it was fine but now it seems to be getting worse. Is there a way of fixing this with out taking everything out of the tank? If not anyone have a link i can go to on how to repair it?

I would think you should be able to drain the tank low enough to reseal it with silicone. Just be sure to let the silicone completely cure before refilling.

To reseal it do i need to take out the old silicone? If so should I just scrape out to where the leak is or the whole corner?

I would remove any loose silicone if any and then reseal over any remaining. Feather the new silicone into th old to get a good overlap. Also try using some masking tape on the glass to make a clean edge so it doesn't get all sloppy. I've done this to old tanks and ended up with a "factory smooth" seal.
