Collection: Hygger Powerheads & Gyres

Two different kinds of flow

Gyre pumps run a long cross-flow rotor that sends a wide band of water down the tank, which helps in displays where rock creates dead spots. A standard powerhead does the opposite job - a tighter stream from one nozzle, simple to point wherever it is needed. Both are stocked here: 5000, 7000 and 9000 gyres for whole-tank circulation, and the 360 Mini and Mini powerheads for directed flow in smaller aquariums.

The range at a glance

• Gyre pumps offered as 5000, 7000 and 9000.
• 360 Mini powerheads at 530 and 1056 GPH.
• Mini Powerhead at 1320 GPH.
• Double powerheads carrying two heads, at 2 x 1050 and 2 x 2100 GPH.

Getting placement right

Published flow ratings are measured in open water, so the figure on the box is not what arrives at the opposite end of a rockscaped tank. A gyre works best mounted along the back glass with its output running the length of the aquarium, and a powerhead should sit well above the substrate so it does not lift sand. For fish that prefer calmer water, two smaller heads spread across the tank usually beat a single high-output pump.
