Neptune Systems DOS Quietdrive Dosing and Fluid Metering System

The DŌS QuietDrive is a high-precision, multi-purpose dosing and fluid-delivery system designed to automate key tasks in reef and marine aquariums. Its whisper-quiet stepper-motor drive and leak-proof compression fittings deliver exceptionally reliable, consistent dosing — from tiny micro-doses (as little as 0.1 ml) up to flows of 250 ml/min — making it ideal for everything from calcium/alkalinity maintenance to liquid feeding and even automated water changes. Once connected to a compatible controller (e.g. an Apex system with the correct outputs), the system integrates with the controller’s management software so dosing schedules, water-change routines, or automated supplement delivery can run without daily manual effort.
