Hi all, bought a second hand Redsea MAX, is this silicone failing?
Reading all of the horror stories online has me worried lol

Put some straps on it if you can, and get a tub to hold any livestock you've got. Another user has a similar defect and his tank called pretty quick.

Woo boy, glad you have a new tank on the way. That would be keeping me up at night knowing how these tanks behave nowadays.
