The CITR3 Pro’s versatility and ease of use make it a valuable addition to any aquarium. You can use the CITR3 as a refugium to improve filtration by growing and harvesting macroalgae, as a designated space for cultivating small organisms like copepods and amphipods as food, or even as an acclimation or isolation box for new or injured fish and corals. The in-tank, high flow design allows tank inhabitants to regenerate damaged tissue without the need for a separate quarantine tank. Adjustable hanging bracket and pump included. The bracket on the CITR 3 PRO will fit rimless and rimmed tanks up to 1.25” thick and will fit tanks with euro bracing up to 0.50” thick.
