Hey guys, i'm new to this site and was hoping you guys could give me some advice and tips on resealing tanks. I just bought a beautiful 35 gallon hexagon tank for a great deal. It didn't even cross my mind to check the silicone (as this is an old tank). When I started to fill it up with water it had a huge leak in one corner. Its not a crack in the glass just some worn out silicone. I'm super nervous about resealing it. Its a beautiful tank and i'd hate to mess it up. If ya'll have any suggestions on how I should go about it i'd love to hear them. Also, if the leak is only on one side can I just reseal that one side, or should I reseal the entire thing? I'm really nervous about having to do the entire tank because there's a lot of sides to it. Thanks in advance.
