A wave maker is a small pump that pushes water around an aquarium to create current and surface movement. Tanks with corals often use stronger, programmable models, while freshwater tanks may only need a simple powerhead. Flow figures are the main spec, but they appear in gallons per hour, gallons per minute or liters per hour, so units need a close look.
The six wave makers below come from the listing pages on Amazon.com. We have not used them ourselves. Flow, noise and tank-size claims are the makers’ own, and where a listing mixes units we say so.

What to Look For
| Feature | Why it matters |
|---|---|
| Flow rate | Compare in the same unit: 1 gpm equals 60 gallons per hour |
| Tank size | Makers give a recommended range; match it to your tank |
| Mounting | Suction cups, magnets or glass-thickness limits |
| Controls | Fixed output versus programmable wave modes |
| Power | Mains voltage or a 24V DC driver |

The 6 Best Aquarium Wave Makers
1. FREESEA Magnetic Wave Maker
A black submersible pump listed at 26.67 gpm and 8 watts on 120V that slides along 15 mm (0.6 inch) glass with a magnet, so you can move it without unplugging. The maker aims it at 55 to 125 gallon tanks and says it works in saltwater and freshwater. It weighs 1.3 pounds.
Suits: larger tanks where the layout changes. Strengths: a magnetic mount that repositions quickly. Weaknesses: limited to a specific glass thickness. Skip it if your tank glass is thicker or thinner than 15 mm.

2. hygger HG070 Cross Flow Wave Maker
An 18 watt, 24V DC cross flow pump with a maximum of 7000 liters per hour and an LED display controller. The maker lists five wave modes: pulse, sine, constant, random and cross flow. The pump is magnetic and weighs 0.84 kg.
Suits: reef and planted tanks that want varied flow. Strengths: programmable modes and a wide flow. Weaknesses: needs a controller and wiring. Skip it if you want a plug-in powerhead.

3. DaToo Mini Wave Maker
A 3 watt stainless steel pump measuring about 1.18 by 1.18 by 2.68 inches with a rotating ball joint for 360 degree aim and a suction cup. The title states 800GPH but the specs say 800 liters per hour, a gap of nearly four times, so the real flow is unclear.
Suits: a small tank that needs a tiny pump. Strengths: a very compact body. Weaknesses: conflicting flow figures. Skip it if you need to know the exact flow.

4. AQUANEAT Circulation Pump 2 Pack
A pair of 800 GPH pumps, each 13.33 gpm and about 3.25 by 2.5 by 2.5 inches, with suction cups and ball joints for 360 degree rotation. The maker suggests 75 to 120 gallons for freshwater and 60 to 75 gallons for saltwater, and says not to connect a timer or controller to the pumps.
Suits: crossing two flows in a large tank. Strengths: two pumps in one pack. Weaknesses: no controller support. Skip it if you want programmable waves.

5. Fluval Sea CP3 Wave Maker
A compact circulation pump, 4.3 by 7 by 5.1 inches and 16 ounces, with a 270 degree adjustable nozzle and a suction mount. Fluval gives a maximum flow of 2800 liters per hour for tanks up to 50 gallons in freshwater or saltwater, and says it is made in Europe.
Suits: tanks up to 50 gallons. Strengths: a known aquarium brand and a movable nozzle. Weaknesses: no wave modes. Skip it if your tank is larger than 50 gallons.

6. AQUASMITH Gyre Wave Maker
A 20 watt, 24V pump with a listed flow of 15000 liters per hour (3962 GPH in the title), a wide cross flow outlet, eight flow modes including pulse, interval, tidal and turbulent, and a custom mode with 100 levels of control. The maker says a sine wave drive and silicone damping reduce noise.
Suits: large reef tanks. Strengths: the strongest flow here and many modes. Weaknesses: a mounting method is not clear in the text we read. Skip it if your tank is small.

Care and Setup
- Keep the pump fully submerged when it is running.
- Aim flow along the glass instead of straight at plants or decor.
- Rinse the impeller on a regular schedule to keep flow steady.
- Unplug a pump before you move it or clean it.
Mistakes to Avoid
- Comparing GPH and L/h figures as if they were the same unit.
- Buying for a tank much larger or smaller than the range.
- Adding a timer to a pump the maker says not to use one with.
- Pointing a strong jet at loose substrate.
Wave Maker FAQ
How do I convert flow units?
Multiply gallons per minute by 60 for gallons per hour, and multiply gallons per hour by about 3.8 for liters per hour.
Which models are programmable?
The hygger HG070 and AQUASMITH Gyre list wave modes. The others run at fixed output.
The Short Version
For a magnetic mount, the FREESEA. For a controller and five modes, the hygger HG070. For a tiny pump, the DaToo. For a two-pump pack, the AQUANEAT. For a tank up to 50 gallons, the Fluval CP3. For eight modes and a large reef, the AQUASMITH Gyre.
