Rawr.

I have had such a darn journey to get this tank set up. Bought a brand new tank to avoid issues - and what do we have...

Tank has been set up for 2 months, just discovered this...

Almost at the very top. Bubble in main seal. 125 gallon perfecto tank.

What do I do... I'm about to pitch a fit if I need to drain this thing.
