I would check the level of your buffer before you run.  Make sure it is right up to the rim and then watch to make sure the level doesn't drop, it is probably leaking.  Fill your inner chamber first and watch it before filling the outer chamber.

Have you removed the white seal at the bottom of the gel?

Is the buffer leaking out when a dummy gel is attached? Perhaps the
"real gels" form a better seal on the tank than the dummy.
