For years, all-in-one aquariums have been limited to small volumes and insufficient out-of-the-box features. Most of tanks that saw mainstream success stayed around 30-gallons or less, with just about all of them coming with inadequate filtration for a fully functional reef aquarium. Even adding extra equipment proved to be difficult, as the rear chambers of these tanks were often too small and the built-in lid limited what you could put in the back. Innovative Marine changed all that when they introduced their NUVO line of aquariums. The sleek, open-top aquariums had huge rear chambers for additional equipment, and they even made solid performing protein skimmers and media reactors that could easily fit. After a couple of very successful years, IM has expanded their initial lineup to include the all new Shallow Reef (SR) series, which was designed specifically from a hobbyist standpoint. The new SR tanks come in three beefy sizes of 60, 80 and 120 gallons MORE: Innovative Marine NUVO SR Series Brings Beauty and Function to Large All-in-One Aquariums
