New updated grate design with 20% greater flow than previous model.
You can use the CITR3 as a refugium to improve filtration by growing and harvesting macroalgae. The CITRs also function as a culturing area for small organisms that are intended to be provided as a food source for the inhabitants of the main portion of the tank. The versatility and easy use of the CITRs make them a valuable addition to every aquarist’s tank.
The CITR In-Tank Refugiums are “safe houses” that provide a protected area to help newly added fish or invertebrates easily acclimate to a new tank while also providing a place for injured fish or corals to regenerate damaged tissue without the need for a separate quarantine tank.
The CITR 3 and the CITR 3 PRO both have slots cut out of the side, so that depending on circulation around the unit, a pump may not be required. Available with (DX model) or without pump.
