Hydor Koralia Nano 240 GPH Powerhead is a nano AC powerhead rated 240 GPH. On its own it supplies comfortable flow for about 10 gallons of soft coral, 10 gallons of mixed reef, or 5 gallons of SPS, before placement and mode settings.
Hydor Koralia Nano 240 GPH Powerhead: fits roughly 5-20 gallon systems. Specs, compatibility math, sizing risks, and alternatives before you buy.
Who it is for
Good fit for
- ✓ 5-20 gallon systems, per the catalog fit range.
- ✓ About 10 gallons of mixed reef or 10 gallons of soft coral on its own.
Not a fit for
- ✕ Systems over about 20 gallons without adding capacity elsewhere.
- ✕ SPS tanks over about 5 gallons unless paired with more flow.
Listed features
- AC
- non-controllable
- magnet mount
- cage propeller
Compatibility math
Turnover contribution
Example: 240 GPH contributes about 3x turnover on a 75g tank before placement and mode settings.
The planner adds all flow pumps together and compares the total to the reef goal.
Risk notes
- Too little flow leaves dead spots. Too much direct flow can strip tissue from LPS and irritate soft corals.
Professional fit context
- Check controllability, broadness of flow, glass thickness, GPH range, and whether two smaller pumps beat one large one.
- Hydor Koralia Nano 240 GPH Powerhead fits roughly 5-20 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
Alternatives to compare
- Tunze Turbelle Nanostream 6055 Controllable (250-1450 GPH)
250 GPH vs 240: more flow.
- Sicce Voyager Nano 250 GPH Stream Pump
250 GPH vs 240: more flow.
- Tunze Turbelle Nanostream 6015 (475 GPH)
475 GPH vs 240: more flow.

Questions
How many Hydor Koralia Nano 240 GPH Powerhead pumps does a 75 gallon mixed reef need?
A 75 gallon mixed reef wants about 2,250 GPH of total flow by ReefCrafter's 20-40x rule. At 240 GPH rated, that is about 10 of these at full output, before return-pump flow and mode settings.
What tank size is the Hydor Koralia Nano 240 GPH Powerhead for?
ReefCrafter's catalog fit range for it is 5-20 gallon systems. Confirm that against your final display volume, sump volume, and livestock plan rather than the box label alone.
What should I compare the Hydor Koralia Nano 240 GPH Powerhead against?
Tunze Turbelle Nanostream 6055 Controllable (250-1450 GPH) (250 GPH vs 240: more flow); Sicce Voyager Nano 250 GPH Stream Pump (250 GPH vs 240: more flow); Tunze Turbelle Nanostream 6015 (475 GPH) (475 GPH vs 240: more flow).
