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
Some of us with the version 2 are having the issue. There are caps over the spiral silencers. and it would seem that the water is coming into the overflow but not with sufficient surface skim. if you don't have the dull layer at the surface them you are fine.
