Red Sea REEFER-S 700 G3+ Aquarium & Cabinet

£4,249.00

The REEFER-S G3+ range is Red Sea’s super-sized reef system – extra depth and height give you far more room to aquascape, and serious volume for a stable, thriving reef. At 700 litres total volume, it’s a large reef with room for bigger fish and impressive coral growth.

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 S-700 G3+, which includes all the core Red Sea equipment.
