Red Sea Reefwave 25 7500lph
Broad, gyre-style cross-flow that behaves like a real reef current, not a single jet. The Red Sea ReefWave 25 pushes up to 7,500 L/h of water movement across the tank in wide, alternating sheets, controlled from the ReefBeat app or the included dedicated controller. It runs forward and reverse, mounts horizontally or vertically, and is sized for marine and reef aquariums roughly 45 to 120 cm in length. This listing is for the pump unit, supplied per Red Sea's specification with its dedicated controller and mains power supply included.
Key features
- Gyre cross-flow technology spreads up to 7,500 L/h in broad, even sheets across the tank
- Adjustable flow intensity from 10% to 100% of maximum, set via the ReefBeat app or the dedicated controller
- Forward and reverse flow direction for full-tank circulation and randomised wave patterns
- Silent-drive magnetic-mount motor; installs horizontally or vertically, submerged at least 5 cm below the waterline
- Built-in Wi-Fi for ReefBeat app control of schedules, wave programs and feed mode

Performance
Red Sea publishes 7,500 L/h as the maximum output at 100% intensity, but has not published a flow-by-percentage (L/h) curve for intermediate settings, so we can't state an exact output at, for example, 50%.
| Flow setting | Output | Guidance |
|---|---|---|
| 100% (maximum) | 7,500 L/h | Full-strength gyre cross-flow for larger or heavily-stocked reef tanks |
| 10% (minimum) | Not published by Red Sea | Gentle, low-turbulence flow – useful overnight, during dosing or feeding, or for more delicate livestock |
The 45–120 cm recommended tank length isn't tied to a specific flow setting, so treat it as a general sizing guide rather than a setting-by-setting chart. A noise (dB) rating hasn't been published for this model, though Red Sea markets the ReefWave range as a silent-drive design.
Assuming continuous 24-hour operation (Red Sea hasn't specified a typical duty cycle) and the published 4–25 W draw, running costs work out to roughly 35–219 kWh per year – actual use will usually sit lower, since most reef keepers vary flow intensity rather than running at full output constantly.
Suitable for, and not suitable for
Suitable for: marine and reef aquariums from about 45 cm to 120 cm in length, with glass or acrylic up to 15 mm thick, where broad, low-turbulence cross-flow is wanted for coral health and detritus control.
Not suitable for: tanks with glass or acrylic thicker than 15 mm, or installations where the pump can't be submerged at least 5 cm below the waterline. Red Sea's documented suitability for this model is marine and reef aquariums; freshwater use isn't specified.
Care and maintenance
Rinse the pump housing and gyre impeller periodically to clear coralline algae and debris – reduced flow output is often a sign the impeller needs a clean. Wipe the external mounting magnet and the glass beneath it regularly, since algae or calcium build-up there can weaken the magnetic hold and cause the pump to slip. Red Sea sells impeller sets and other spare parts separately for when parts eventually wear out.
Safety
This is a mains-powered aquarium device. Connect it through a residual current device (RCD/safety switch) suited to AU wet-area wiring, and run a drip loop in the cable before it reaches any power socket or board. Use only the power supply provided, and disconnect power before servicing the pump or handling the magnets.
Goes well with
Spares such as replacement impeller sets, motor assemblies and mounting magnets are available separately from Red Sea for when service parts are needed down the track.
Warranty and delivery
This product is covered by the manufacturer's warranty in addition to your rights under the Australian Consumer Law, which apply regardless of any manufacturer warranty terms. The included power supply is set up for the Australian market at 230–240 V, 50 Hz.
Common questions
Can I control the ReefWave 25 from my phone?
Yes. It has built-in Wi-Fi and connects to the free ReefBeat app, where you can set flow intensity, wave patterns, schedules and feed mode. A dedicated physical controller is also included.
What tank sizes is it recommended for?
Red Sea recommends it for tanks roughly 45 cm to 120 cm in length, with glass or acrylic up to 15 mm thick.
How much power does it use?
Power draw ranges from 4 W to 25 W depending on the flow setting.
Does it come with a controller?
Yes – Red Sea's specification for this model lists a dedicated controller and mains power supply as included with the pump.
How is it mounted?
It uses a magnetic drive mount and can be installed horizontally or vertically, submerged at least 5 cm below the waterline.
Is it suitable for a freshwater tank?
Red Sea documents this model for marine and reef aquariums; freshwater suitability isn't specified.
