my tank just started leaking water out the bottom. it was not moved, nothing fell in it. this has not happened to anybody i know?

sometimes the seam quality is just not up to snuff.....is the tank loaded evenly? {do you have a lot of weight on one area.}.............it really is amazing how much pressure is on these aquariums .........lbs per square inch....and rock placement and or lack of rock placement or just good old fashioned thin silicon can allow water to work its way through .......................dry repair is the only fix though ...temp fixes will only temp fix......not repair....lol Boss
