The 3rd Generation Refugium features Eshopps' patented Channel Design, which enables water to flow through two separate water channels at the same time, improving natural filtration and the water quality in your reef aquarium!
Water enters your refugium through the micro filter bag in the first compartment. From there, water can travel through either of the two remaining compartments.
The Refugium Compartment provides space for you to raise macroalgaes, which help naturally remove ammonia, nitrates and other excess nutrients that are harmful to aquariums.
Water can also travel through the Skimmer Compartment, where smaller particles and dissolved waste can be removed by your protein skimmer (sold separately).
The R-100 model includes a single intake with a 4 in. micron bag and is rated for reef aquariums 75-125 gallons.
Overall Dimensions (LxWxH): 24 in. x 12 in. x 16 in. Skimmer Compartment: 8 in. x 11.5 in. Refugium Compartment: 10 in. x 7 in.
