Flow Is What Corals Actually Feel

A return pump moves water through the sump; powerheads and gyres move it around the display. Corals need varied, turbulent flow to shed detritus and feed properly, and dead spots are where cyanobacteria and detritus settle. Random or pulsing flow beats a constant jet aimed at the same rock.

Propeller, Gyre or Cross-Flow

Propeller powerheads — compact, high-output, controllable units for broad random flow.
Gyre pumps — a crossflow design that pushes a wide sheet of water down the tank's length.
Cross-flow pumps — a rolling flow pattern for even coverage in wider displays.
Nano and non-controllable pumps — simple fixed-output powerheads for small tanks and utility duty.
Spares — replacement wet sides, foam guards and mounts.

Two smaller pumps facing each other usually produce better turbulence than one large pump on full. Not sure what suits your tank? Email info@jlaquatics.com.

J&L Aquatics was formed in December 1997

Our business was started from our love of the aquarium hobby. We at J&L Aquatics felt that the Canadian aquarist should have the option to purchase top quality supplies, equipment and livestock other than the generally over priced local retail stores.
