Red Sea REEFER MAX 300 G3+ Complete Reef System

The Red Sea REEFER MAX 300 G3+ is the complete, ready-to-run version of the REEFER 300 G3+. 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. The MAX package adds all the core Red Sea equipment – lighting, flow, skimming, roller-mat filtration and smart control – matched to the size of the tank, so everything works together from day one. At 300 litres total volume, it’s a versatile mid-size reef with plenty of room for a mixed coral and fish community.
