So I get a frantic call from the wife, there's water on the floor around the fish tank, pull up the Apex and shut down everything but the MP40 and head home.
Apparently one of my bulkheads had loosened about 1/4 of a turn to where there was a very slow drip down the back of the tank on to the floor. Only lost about 1/2 a gallon or so.
I checked the other two bulkheads and they were both loose about 1/8th of a turn so I tightened them back up as well.
TLDR: Check the tightness of your bulkheads periodically!
