What can I add to my tank...

Make it into a closed loop. Duct tape a funnel on the glass, short piece of old garden hose jammed onto end of funnel and back up into the tank. I will leave the mode choice of moving the water back into the tank to the real gingeneers.

That's one I hadn't thought of! Just not sure where it's leaking, the bottom trim is full of water. Nice effect of salt creep moving up the front glass though!
