DŌS – Dosing and Fluid Metering System

• Easy Setup via the Apex Fusion Interface
• Great for Two-Part Dosing or Automatic Water Changes
• Precision Dosing with Flow Rates from 0.1mL to 250mL/min
• Easy-to-Replace Dosing Heads

The Neptune Systems DŌS is a highly efficient, programmable dosing system designed to work seamlessly with the Neptune Systems Apex Controllers. Ideal for a variety of dosing applications, it offers precise control over dosing volumes and schedules through the easy-to-use Apex Fusion cloud interface. The DŌS pump features dual pump heads, large-diameter tubing for less wear and quieter operation, and simple maintenance with easy tube replacement. It's a practical solution for accurate and consistent aquarium dosing, minimizing manual work and maximizing reliability.

What Can the DŌS be Used For?

Two-Part Dosing: The most common use for the DŌS is dosing calcium and alkalinity to your system. Using a dosing pump to add these elements means greater stability of important water parameters and less daily maintenance. Simply run the DŌS Additive Dosing task in Apex Fusion and enter the amount of liquid you'd like to dose and when you'd like for it to be dosed. The DŌS then sets up all the dosing intervals within that time period. It even automatically chooses the slowest speed necessary for the pump so that it minimizes noise.

Automatic Water Changes: Water changes with the DŌS have never been easier.  All you do is run tubing to your empty vessel or drain and to your fresh stock of saltwater. Then, in Apex Fusion, select and run the DŌS Automatic Water Change task and you'll be up and running in a matter of minutes. It will perform an automatic water change for you based on the schedule you've set up. If you have optical sensors, you can even set up alerts when your fresh saltwater container is running low.

Micro Dosing: If you need to dose tiny amounts liquid (like vodka dosing or for Zeovit systems), the DŌS is the perfect solution due to its precision-controlled stepper motor. This ability to control pump movement in such a refined manner means that you can dose as little as 0.1ml at a time.

Easy Maintenance and Tubing Changes

Changing out the pump head on the DŌS is a snap...Literally! All you need to do to change out the pump head is squeeze and remove. Then attach your dosing tubing to the new head, and snap it back on. No screws, no fuss.

DDR Compatible (sold separately)

The DOS has an accessory port that will enable it to be connected to the DDR – DOS Dual Reservoir. The DDR has two storage vessels that hold up to 2 liters each, with an optical sensor in each side to let you know when you're running low on dosing solution. Note: alcohol-based products should not be stored in the DDR.
