Benjamin Duncan –
The REEFER 170 G3 is easy to set up and looks great in my home. The rimless design fits well with my existing decor. The auto top-off system has been reliable since I installed it. I’m happy with the build quality and the clean lines of the tank.
Joan Morgan –
I chose the white stand for a modern look. The tank is sturdy and the plumbing is well organized. I’ve added my own skimmer and lighting, which works perfectly with the system. Only minor adjustment needed for the flow valve.

This tank has made reefkeeping much more manageable. The ReefATO+ system saves me time every week. The glass is thick and the sump is stable. I’m impressed with how well it integrates with other equipment.
