The summary

  • What you receive: the pump on its own, with its adjustment knob and its 4/6 mm outlet.
  • What sets it apart: 2 metres of head for 2 watts, and a flow rate that can be adjusted continuously.
  • How to choose: this one for a tall tank or a current that needs fine control, from 20 to 150 litres.
  • Where to place it: above the water level, or with a non-return valve on the pipe.

An adjustable aquarium air pump, which delivers air at a depth of 2 m for 2 W

The Aquael Oxypro 150 air pump is used to aerate an aquarium of 20 to 150 litres. It delivers up to 150 litres of air per hour for 2 W, with continuously adjustable flow. It stands out for its ability to push air down to 2 m below the surface, which suits tall tanks and airlift filters.

With an aquarium air pump, the decisive figure is less the flow rate than the depth to which the air is still pushed: a tall tank, an airlift filter placed at the bottom or a pipe that takes a detour is enough to stop an ordinary pump. The Aquael Oxypro 150 pushes air down to 2 m below the surface for a power of 2 W, with an adjustable flow of up to 150 litres per hour, for an aquarium of 20 to 150 litres.

📉 2 metres for 2 watts

An entry-level air pump delivers at a depth of 60 or 70 cm, whereas this one reaches 200 cm. In a tank 50 cm tall, this reserve goes unnoticed, but it gives you the margin you need for a long pipe, a T fitting, a fine diffuser that offers resistance or a stone that clogs up. In a 70 cm tank fitted with an airlift, it becomes the condition for the air to actually come out at the bottom.

Adjustable flow rate

A large knob varies the air output continuously, from a few bubbles up to 150 litres per hour.

The depth, constant

The pump pushes air down to 2 m below the surface: this is its maximum delivery head.

🎛️ What the adjustment is for

The electronic flow adjustment lets you calm a planted tank, where overly strong circulation drives off dissolved CO2, reduce the current for fish that swim little, push the aeration to maximum during a heatwave and then bring it down again, and meter the suction of a venturi. The dial turns continuously, without notches, so you can find the right flow for each season. The article on maintaining an aquaponic system in summer goes back over the periods when aeration needs to be increased.

Siphoning, and how to avoid it

An air pump placed lower than the surface of your tank fills with water as soon as it stops: the water runs back down the pipe and into the pump body. Place it above the water level, or fit a non-return valve on the pipe. A closed aquarium cabinet is the worst possible place, since the pump sits there at floor level and below the tank.

A diffuser bar at the end of the pipe

The 25 cm quartz sand diffusing bar connects to the 4/6 mm pipe of this pump and spreads the air into a curtain of fine bubbles along its whole length. Laid on the bottom of a tall tank, it creates a resistance that the Oxypro 150's 2 m of delivery head absorbs without difficulty. You therefore stir the whole width of the tank instead of a single spot.

🔇 Silence and installation

The transparent casing lets you see the moving diaphragm, and an LED shows that the unit is running. Its design aims for silence: a sound-insulation chamber, a double wall and feet that absorb vibration limit the noise transmitted. The surface it stands on still matters, though, because a hollow board, a cabinet lid or a pane of glass acts as a sounding board and amplifies the slightest vibration. Place the unit on a piece of foam or a folded towel, and you can leave the aeration running at night, when photosynthesis stops and the dissolved oxygen in your tank falls.

🐟 Aeration in aquaponics

In a small indoor aquaponic system, dissolved oxygen is shared between the fish, the biofilter bacteria, which use it to convert ammonia into nitrite and then nitrate, and the roots of the crops. Adjustable aeration lets you increase the airflow when the fish load goes up, without touching the circulation pump, which alone controls the system's water flow. Its 2 m depth rating also allows it to feed a diffuser at the bottom of a tall tank, where a small air pump can no longer deliver. The nitrogen cycle in aquaponics explains why oxygen consumption follows the load on the system.

Which air pump for your tank?
