Neptune DDR – DŌS Dual Reservoir

Stylish, Smart Fluid Storage for Aquarium Dosing Systems

The Neptune DDR – DŌS Dual Reservoir is an attractive and functional fluid containment system designed specifically for your DŌS dosing system. It securely stores your dosing fluids while notifying your Apex controller when fluid levels run low.


Key Features

  • Two separate 2-liter (2000ml) fluid chambers

  • Integrated optical sensors detect low fluid levels

  • Connects directly to your Neptune DŌS

  • Durable, cast-acrylic construction

  • Stable, low-profile no-tip design

  • Easy-lift lids for effortless refilling

  • Push-fit tubing connections

  • Perfect for 2-part dosing (Alkalinity/Calcium) and other aquarium additives


Designed for Convenience and Reliability

The DDR’s sleek design makes it a standout in any aquarium equipment setup while providing ample capacity. For most reef tanks, each 2-liter chamber offers enough solution for up to two weeks of dosing.

The low center of gravity ensures added stability — preventing accidental tipping, even in tight spaces.
