Yeah and the top up reservoir can be easily removed, replaced or supplemented with a @Reefloat atu. Or it can be used as a refugium.
I have now seen the Reefer in the flesh and it is a quality piece of kit. Knocks spots off the signature range in my humble opinion. The finish of the cabinet is on another level compared to that of the TMC ones. The tank looks thick and solid as does the black glass weir which is a definite improvement on my acrylic clad weir which is a PITA to clean.
