Long crack lines appear upon filling up of "new" used tank!! Help!!!

[|JTBC|]

The before cracked picture notice there is an area of shine at the left top bracing where the crack start.
The wooden planter is not designed to take heavy load. Probably you need to have solid support direct to ground.
It is lucky that it crack now then later.
Dun think of saving, Safety is umost important.

The wooden planter could be the problem i think.
It will move slightly in accordance to heavy weight.

Ts ask the tank maker to make a low profile rack 6 legs.
Act as support.

When your new tank is in.
Keep us updated 😁

The bright shiny spot looks to me like an air bubble or lack of silicon filling. Any close-ups of the location?

There isn't planter area underneath the tank. All is solid concrete below the decking...

The top shiny part where the crack began is a part near the top bracing. It seems like there isn't any silicon and lotsa tiny bubbles at that area. Was already there when collected my tank. Have attached a pic for reference... sorry not so clear as just taken. Clearer if taken during the day...

Weird thing is the crack line had gotten longer and longer as the day goes by even without filling up with water... initially was 3/4, yesterday was about 4/5 and today is 9/10. Crack line reaching the bottom already...

First day:


Now:

typical characteristic of glass, fracture only gets longer.

i don't think it's imbalance of weight. could be just 'that' lemon tank. see what tank maker says.
