GW 1,500 Perfect for nano aquariums and smaller systems up to 150L. Compact, efficient and ideal where moderate turnover and minimal power use are priorities. GW 3,000 A versatile option for small to medium systems between 100–200L. Provides stronger flow while remaining compact and economical to run. GW 4,000 Well suited to medium reef aquariums around 200–400L. A balanced option offering strong circulation without oversized plumbing requirements. GW 6,000 Designed for larger reef systems between 400–600L. Increased flow and power range make it ideal for higher turnover sump systems. GW 8,000 Built for large aquariums between 600–800L. Provides powerful circulation and reliable performance for larger filtration systems. GW 12,000 The flagship model. Delivering 12,000 litres per hour, this pump is designed for large reef systems and aquariums approaching 1,200L, where high turnover and substantial filtration flow are essential. Understanding the Specifications Flow Rate (LPH) Measured in litres per hour, this indicates how much water the pump can move. Higher flow rates are generally suited to larger aquariums and higher sump turnover. Power Range Because the pump is fully controllable, power consumption varies with speed setting. This means you only use the energy needed for your system. Inlet / Outlet Size These measurements determine plumbing compatibility and help ensure optimal flow through your return system. Pump Size Physical dimensions matter when fitting pumps into tighter sump chambers or cabinet spaces.
