Hard to tell from that picture, is it at the front of the tank? It might be water thats dripped down and gathered in the plastic liner accross the bottom of the tank? Looks like calcification or something like that.

I thought this too when I saw the pic. how old is your tank? could you possibly get a clearer pic?
inside or outside of the tank. I suppose if it is on the inside you will have to take the fish and water out and seal it. You can buy sealent.
