Bowfront seam failure?

[Delphinus]

Thanks for the info Jason.

The spot you describe is where I seem to have the most water accumulating, a few inches offset from the overflow. It is then running forward spilling out at the front as well as in this spot.

I have run a paper towel "bandana" around the tank to confirm 100% that it is not some kind of spillage from the top. Bone dry.

Yet there is accumulation of water around the bottom trim at the order of a few ml per every few hours.

How long did yours go on like this before you replaced the tanks? I guess now that I have confirmed my diagnosis I'm a bit freaked out as to how far away a catastrophic failure might be. Even flat out I won't have a new tank to transfer into for at least a day or two, and this has been going on for several days now already.

Great .... I didn't need to sleep tonight!!!!!!!!
