£1,699.00
The REEFER G3+ range is Red Sea’s best-known reef-ready aquarium system, designed so you can set up a clean, modern reef tank without the hassle of building your own sump and plumbing. At 300 litres total volume, it’s a versatile mid-size reef with plenty of room for a mixed coral and fish community.
This version gives you the aquarium, cabinet and sump, so you can choose your own lighting, flow and filtration. Prefer a complete package? Look at the REEFER MAX 300 G3+, which includes all the core Red Sea equipment.
