Introducing the Neptune Systems DOS QuietDrive, a state-of-the-art dosing pump equipped with features that cater to the needs of the modern aquarist. This FAQ guide addresses common questions about the DOS QD, providing insights into its performance, setup, and benefits.

How does the DOS QD significantly reduce noise?

The DOS QD incorporates EcoTech Marine's QuietDrive technology, which dramatically minimizes noise levels during operation. Users can expect:

  • High-Speed Operation: At settings of 60/125/250 ml/min, noise is reduced by up to 400%.
  • Low-Speed Operation: At slower rates of 7/12/25 ml/min, the reduction is up to 200%.

This makes the DOS QD an ideal choice for environments where noise reduction is crucial.


Is an Apex Controller required to operate the DOS QD?

Yes, the DOS QD requires one of the Neptune Systems A2 or A3 series Apex Aquarium Controllers. This integration allows for precise control and monitoring through the Apex Fusion software, enhancing the overall functionality and user experience. The DOS QD is not compatible with the A1 Apex Classic.


What are the benefits of integrating the DOS QD with the Neptune 1LINK System?

The integration with the Neptune 1LINK System simplifies installation by eliminating the need for a separate power supply. This system enables both power and data to be transmitted through a single 1Link cable from the Apex Controller, reducing cable clutter.
