Neptune DOS QD – Dosing and Fluid Metering System

Neptune DŌS QD is a QuietDrive dosing and fluid-metering system for an A2 or A3 Apex aquarium controller. It can schedule measured additions of supplements or support automatic water-change routines through Apex Fusion.

Choose the application before routing the tubing: supplement dosing, removal of aquarium water and delivery of replacement water each need the correct source and destination. Calibrate and verify delivery using the manufacturer's setup workflow, and keep the containers accessible for refilling or emptying.

QuietDrive focuses on reducing operating noise while retaining adjustable delivery. Compatible Trident integration can support controlled dosing, but that requires the appropriate analyzer and configuration. DŌS QD is not a standalone dosing controller; plan for its required Apex connection, power and maintenance access.
