Blister on the seal of tank

[pauly187]

i have no idea were to post this
but anyway
like the title says there looks to be like a blister or pimple if you may that has formed on the silcon on the back bottom half of the tank
i just recently moved 8 hours away and when set back up the tank i noticed this blister
need your thoughts
i dont need a leaky tank
this could be just a blob of silacon that was always there and i never noticed
which i think it is cause the blister doesnt seem to be see threw as if it were raising up
the tanks 3months old maybe less and its 135 6ftx18x2ft

Tank will be fine. All that silicone outside the seam is just extra assurance the tank wont leak. It doesn't actually "hold" the tank together.
