The Hydor Koralia is the budget powerhead that actually delivers. Non-controllable, non-programmable, but reliable and quiet at one-fifth the price of the Vortech.

Flow performance

Wide-dispersion flow pattern matches reef flow needs better than narrow-jet alternatives.

Verdict

The default budget choice. Pair two on opposite sides for natural gyre flow.
