I have a 120 gallon too fin aquarium I’m looking to add a sump to. Before any of you suggest a 40 gallon breeder (my preference) the 120 gallon dimensions are roughly 60”x18.5”x26” so a 40 gallon would be the same width. I’m not exactly sure what equipment I’m going to be running in it other than a 4”x6” pump. These are the rough sketches I made. I am looking for any constructive criticism or better baffle layouts.
