Powerheads and Wave Makers: Improving Flow in Your Reef Tank

Water flow is often underrated compared to lighting and dosing, but it plays a critical role in delivering food, oxygen, and preventing detritus buildup on coral.

Why Flow Matters

Strong, randomized flow keeps detritus from settling on coral tissue, delivers planktonic food to filter feeders, and helps maintain even temperature and chemistry throughout the tank.

Powerheads

Powerheads create targeted, adjustable flow and are often positioned at multiple angles to avoid a single, laminar current that can leave dead spots elsewhere in the tank.

Wave Makers

Wave maker controllers vary flow intensity and direction over time, mimicking the natural randomness of ocean currents more closely than a constant, single-direction flow.

Matching Flow to Coral Type

SPS corals like those in our Acropora care guide generally need stronger flow than delicate LPS species like Euphyllia, so plan placement accordingly.
