I am just getting started in reefing and am looking to set up a 20-40 gallon reef tank. Does anyone have suggestions on what AIO tanks are best for beginners? So far I have looked at the Biocube 29g and the IM 20g NUVO Fusion. I'm taking my time and trying to do research and get advise so I can choose a really nice set-up with room for modifications in the future. Any advise would be greatly appreciated!
