Here is a quick peek under the cabinet. The backbone components are Royal Exclusiv and most everything is cleanly contained within the sump. I'm using a BK180 and filter socks. The return is a RD3 pump and it feeds a media reactor that runs GFO. The goal for the sump was silence and organization.
The tank is controlled by a GHL Profilux with dosing tethered to the GHL dosers. I try to keep things as efficiently simple as possible and don't like overcomplicating with more components than necessary.
