So I just recently purchased a All-In-One Nuvo 40 aquarium. I really like these Nuvo tanks. Very good build quality, clear low iron glass, great job on silicone. Just few weeks after setting up my Nuvo, they have now come up with EXT line.

EXT line of aquariums give you a capability to add a sump. So you basically get a full 40 gallons display tank (mine is really a 30-gallons with 10g portion in the back for equipment). With having a sump, you are not constrained to specific type of equipment. Not to mention, you can double your water volume. If I had do it again, I would get an EXT line Nuvo instead. I would highly recommend Nuvo EXT line of aquariums if someone is setting up a small to medium size tank.
