At FrozenQ, our flagship reservoir has also revolved around the helix inside. In order to keep the tradition alive, we've made it cheaper and easier to get your hands on one of these one of a kind helix reservoirs. Open up your LFX 230 or 250 reservoir, drop the helix core in, and that it's! The helix then becomes illuminated by the central tension rod. Model: 850737003344.
