Tank sprung a leak?

[galantra]

Woke up the other morning to leak alarm to my 150 DD marineland tank dripping water(very fast). About a quarter of the water was drained from the tank during that time. Stun and mortified to water all over the floor. Searching to find a cause. Sump was fine but water kept pouring from
Above the stand. Had to search for a method of what to do. Found a bin relocated rock and fish into it and drain the tank completely. As I slowly drain the tank it slowly stop pouring out. I can’t find a crack and only conclude that is must be in the seems.

Should I bother trying to repair it? Or think it might be a bigger issue?

Before you go drastic steps I would look into the following things
1. Any recent changes to ATO placement, air line tubing, ect that could create a back-siphon issue?
2. Any thread used that can cause water to creep?
3. Anything peculiar about where the water is pooling? (front, back, corner)
4. Can you dry the tank and tape down some papertowels around the seems?

EDIT: Realized most of my stuff is pointless if you already identified seams as the main issues....

First thing I would do is call or contact Marineland. Their customer service folks are pretty receptive to customer needs from my past experience w/them. Also check, earlier this year they had a recall on a bunch of their tanks (certain sizes & years built) again check with them.

As far as repair, that's hit or miss. Seams can be difficult to seal, from my understanding the silicone used for seals is between the actual glass panels, not just the corner-beads we all see. But I'ld call them first.

Didnt the DD tanks have this as a known issue? I'd call marineland and see what theyll do for you. How old is the tank?

I check the overflow and it still full to the top so no leak of water there and still drains into the sump with no issues. When it was leaking it was more the front corner more than anywhere else, but can’t find anything but seems looks suspect to me. Soon as the tank was about 10percent full it seem like it stopped. Gonna try and take it down and outside to test. But I can’t lie this makes me wanna stop all together
