I am looking at the endless array of equipment and trying to piece together 2 tanks and components. I am interested in gathering opinions on AIO systems instead of doing a sump. I am currently thinking about a standard Aqueon 120 for my main tank and either buying 2 AIO from FIJI Cube to put inside of it or making an AIO as a DIY. the one advantage of going this route is a bigger display for the same weight as a smaller display with a sump. All pros and cons appreciated.
