The Ghost Overflow is the original name of the design, which was sold with Reef Savvy tanks and was built by Synergy Reef. Synergy now builds their own design and the redesigned Ghost is available from Reef Savvy. There are other manufacturers that have similar designs.
The Bean Animal is not an overflow box, but a drain design that incorporates three separate drains and it can be set up in the outside box of the Synergy Reef & Shadow, Reef Savvy Ghost and other boxes. Those overflows all come with three holes for the Bean Animal drain design. Eshopps does make a box (Eclipse, I think) with two or three drain set ups.
