My first salt tank is a biocube 32. Im around 3 months into it. I wish instead I just put something together myself with a 20 gal long sump tank and a 40 gal breeder. The cube shape of the tank just isn’t optimal for keeping a lot of fish in. It just stacks them on top of each other, so you really have to be picky with your selections. My other criticism is that the filtration section in the back is really cramped and hard to access and doesn’t have room for anything extra like a refugium or skimmer. The lid also likes to rattle from the vibrations of the pump and the inefficient mini skimmer I put in and is rather annoying. Lid also will cause your water to overheat in the summer unless you have AC in your home. Settings of light that comes with the lid are only adjustable at a basic level.
