One Cubic Meter of Ocean

Also the line that feeds up towards the ceiling is from the lower RD return pump, it will later feed a small tank on the floor above, hopefully it makes it.

The line below the bottom sump is just a drain line that feeds to a sink drain. There's a connected overflow in the bottom sump encase the level ever gets too high for some reason. Also a manual drain for water changes and what not. One of the advantages of this system is I can shut off lower sump while the frag tank and display are unaffected. I can then drain and clean the sump, fill it up, heat the water and add salt before activating it again.
