I have custom 80G cube, sump, and stand. I love the tank but the size of the cabinet has always been challenging. Here’s how managed to get a ton of gear in a compressed space including a 7G ro reservoir, a 7G fug, and 2.5G additives. I know I need a cable management but for now everything is routed inside the cabinet. I’d love to see what you all have done in challenging spaces.
