Any suggestion, comments Ect. are welcomed. I am looking at buying a Innovation Marine NUVO 120 AOI. I cannot find many reviews on this setup. Im hoping someone can give me the pros and cons soon, as I plan to go look at it today. I’m currently running a Flex 32.5 and I’m assuming this is just a gigantic flex. I know the downfalls of not having a traditional sump with protein skimmer ect… my concern is how often will water changes be required not having that traditional gear with one blue hippo, a Sailfin two clowns and two pajamas + a ton of corals. I really don’t plan on many more livestock. My goal is to keep a low maintenance tank as I do travel and vacation often. Hens, another reason I like the idea of a AIO as it is “potentially” a safer option for less to go wrong plumbing wise. Thoughts?
