Tank induced stress?

[lastlight]

Yeah that stand was insanely overbuilt but you still hear the thing settle with all that weight on it. Dead level etc but still made a few noises.

The following horror in that saga was when I realized I had tiled the wall the tank was in a little too close to the front pane. It did have some bowing and I couldn't slide a piece of paper between the tile ledge in the front and the pane.

I drained it immediately and ripped those tiles off intending to lay new ones further away from the front.
