Tank induced stress?

[lastlight]

I wonder if anyone's ever gotten a faulty membrane that somehow let their tank fill much faster than expected?

I had jitters with the 225 a bit. Because it's black silicone you can see the seams turn a bit white with the pulling in some spots and that really freaks me out. I would inspect those spots all the time but no issues.

Now the 400 that I had started to build was a different story. My stand made all sorts of creaking sounds as I did the freshwater test and I was pretty damn scared.
