I am not sure if the pyrex walls of this new version are any thicker than the 30.x.
This is an important consideration because the 30.x's tube broke too easily.
Also, take note of the 2 small silicone sleeves at either end ...
These are a real nuisance because they can easily fall off the tube and become lost while washing the tank.
Too many moving parts and too many unknowns to take the risk, in my opinion. You may spend a little more money on the Nautilus or an Aerotank, but have a lot less hassle (and consequently, more spent $$$) in the future.
