My own case that I mentioned earlier was first noticed as MASSIVE water pooling around the bottom seam on my tank and around the base of the tank on the stand. Not good!!
I was freaking out until I figured out that the new pump setup was creating a tiny wave (I mean small!) that would barely touch the top trip ever few minutes. That's all it took for water to get out of the tank. The result (which I eventually found) was that there was a tiny stream of water down the side of the tank that was never very visible since it didn't dry out....I imagine that it was only "flowing" a drip an hour or so, but it adds up!
