CPR Aquatics CITR3 Pro In-Tank Refugium
The CPR Aquatics CITR3 Pro is a hang-in refugium that sits inside your display tank, so all-in-one and rimless systems with no sump space still get a real place to grow macroalgae and raise copepods. Water enters through the included powerhead or the slotted sides, passes through the fuge chamber, and returns to the display. Grow chaetomorpha for nutrient export, culture pods that feed mandarins and wrasses, or use it as a recovery box for an injured fish or a coral frag that needs a break from tankmates. Pair it with a small fuge light like the AI Prime 16 Fuge and seed it with Nutramar Tigrio live copepods.
Features
- Adjustable hanging bracket with a 3.5 inch range, fits rims up to 1-3/8 inch thick
- Powerhead included; side slots allow passive flow, so the pump is optional in tanks with good circulation
- Clear acrylic body so you can watch macroalgae and pod growth
- Compact 7.5 x 4 x 7.125 inch footprint, plus about 2 inches of width for the pump
- Doubles as an in-tank isolation or recovery box
Three ways to use it
- Nutrient export: a ball of chaetomorpha under a fuge light pulls nitrate and phosphate out of the water.
- Copepod culture: pods breed in the macro away from fish, then spill into the display as live food.
- Recovery box: isolate a picked-on fish or a damaged frag in display water without a second tank.

FAQ
Do I have to run the pump? No. With decent flow around the unit the side slots move enough water. Use the pump in dead spots or when you want faster exchange.
Will it fit a rimmed tank? Yes, the bracket clears rims up to 1-3/8 inch thick and adjusts over a 3.5 inch range.
Which size do I need? The Small suits nano and all-in-one tanks. If you are running a larger system, ask us about the Large CITR3 Pro.
