The "control cabinet" I made took about half the room on the left side of the sump, I don't really want to cram another aquarium in there. Ive seen other ATOs that are for lack of a better esthetically pleasing. so I might just go with something that will sit outside of the cabinet. With my previous aquarium I actually had my ATO hidden in ottoman. We'll see what I can come up with.Wow, you went all out. Looks really good!
You have room for a 10 gallon tank as an ATO
That is good for just over a week on my tank
