what refugium tank is being used here?

In this video it introduces benefits of refugiums. It looks really huge, but I really like how much dedicated refugium space that sump has. Does anyone know what that exact product is called and where I can find it?

very likely a custom made acrylic sump. @TopShelfAquatics any input/plug? :)
