AQUAFOREST - AF Reeflow 4500 - 4500 l/h

A high-performance Aquaforest return pump for marine or freshwater aquariums

The AQUAFOREST AF Reeflow 4500 pump is designed for aquarists who want an efficient return pump without excessive noise or high power consumption. In a marine aquarium, especially one with a sump below the main tank, the return pump operates continuously. It must therefore be stable, reliable, and powerful enough to ensure proper water exchange between the sump and the main tank. The Reeflow 4500 precisely meets this need with a maximum flow rate of 4500 liters per hour , while maintaining a low power consumption of 53 W.

It is ideally suited to a reef aquarium equipped with a protein skimmer, reactors, or a complete filtration system, but can also be used in a large freshwater aquarium requiring consistent water circulation. Its 4.4 m return head provides ample power when pumping water from a technical cabinet. The result is simple: proper water circulation, optimal performance of the equipment, and a more consistent and effective water flow throughout the aquarium.

Adjustable flow rate down to the percent for precise control of water circulation

One of the most appealing features of this Aquaforest Reeflow 4500 return pump is its highly precise adjustment. Thanks to its remote controller, the flow rate can be adjusted from 0 to 100% in 1% increments . This level of precision is particularly useful for adjusting overflow, minimizing noise during descent, or finding the correct flow rate in the sump without resorting to guesswork.

This precise control also allows you to adapt the pump to the actual needs of your tank. A young, lightly stocked aquarium won't necessarily have the same requirements as a mature reef with many corals, fish, and technical equipment. The Reeflow 4500 adapts to this evolution without difficulty. It can be set more gently at first, then gradually increased according to the system's configuration. The controller displays operating parameters in real time, making it clear and convenient to use every day.

A silent aquarium pump thanks to DC technology

The Reeflow 4500 uses modern DC technology , prized for its smooth, quiet, and energy-efficient operation. A return pump runs day and night, so noise level is crucial. In a living room, office, or open-plan space, a noisy pump can quickly become a nuisance. Here, Aquaforest has opted for a discreet motor and thoughtfully designed accessories to minimize vibrations.

The four included silicone feet help absorb micro-vibrations and reduce noise transmission to the stand, sump, or cabinet. This allows the pump to operate almost unobtrusively, while still maintaining ample power. This quiet operation is a real advantage for aquarists who want to enjoy their aquarium without constantly hearing the running equipment.

Controlled consumption for a powerful and economical pump

With a power consumption of only 53W and a flow rate of up to 4500 l/h , the AF Reeflow 4500 offers excellent efficiency. This is important because a return pump is one of the pieces of equipment that remains constantly powered on. Better energy management helps limit electricity costs while maintaining a flow rate suitable for the proper functioning of the aquarium.

This energy efficiency makes it an attractive pump for modern reef setups, where every piece of equipment must be carefully selected. It delivers the necessary power without being excessive. For Zoanthus, it's exactly the kind of pump that appeals to discerning aquarists: powerful enough to properly supply a technical setup, yet quiet and understated enough to be pleasant for everyday use.

A flexible installation for immersion, above-water or closed-loop systems

The AQUAFOREST AF Reeflow 4500 was designed to adapt to several types of setups. It can be used submerged , directly in the return compartment of a sump, which remains the most common installation for a marine aquarium with a sump. It can also be mounted above water , in an external configuration, for setups that require a more specific filtration system.

It can also be integrated into a closed circuit , for example to enhance circulation behind the decorations or improve water movement in certain areas of the tank. This versatility provides considerable freedom when designing or upgrading a setup. The included fittings facilitate adaptation to different pipe sizes, with connectors for 20 mm, 25 mm, and 30 mm pipes, as well as two 25 mm hydraulic fittings.

Integrated safety features to protect the pump and preserve the installation

A return pump must be efficient, but above all, it must be safe. The Reeflow 4500 has built-in protections to minimize risks in case of a problem. These include protection against dry running and overheating . If the water level becomes too low or if the pump encounters an abnormal situation, the system is designed to protect the motor and prevent premature wear.

This safety feature is particularly reassuring in a reef aquarium setup, where circulation between the sump and the main tank plays a crucial role. The pump indirectly powers a significant portion of the filtration system, contributes to its overall stability, and supports the operation of numerous other pieces of equipment. With a well-protected pump, the aquarist gains peace of mind and minimizes the risk of unpleasant surprises.
