Neptune DOS Dosing and Fluid Metering System QuietDrive

Whisper-Soft, Accurate Dosing for Aquariums

The Neptune DŌS QuietDrive is a multi-purpose dosing and fluid delivery system of uncompromising quality, combined with the simplicity of Apex Fusion software. Ideal for:

• 2-part dosing (Calcium and Alkalinity)

• Other additives dosing

• Automatic water changes

• Micro-quantity dosing

• Delivery of liquid foods and supplements

Quiet Operation

Nothing detracts from the serenity of a beautiful aquarium like obtrusive equipment noise. The DŌS QuietDrive is engineered in both physical design and motor operation to be one of the quietest dosing solutions available.

The QuietZone continuous duty range also offers greater flexibility for additive dosing and automatic water changes.

Dosing Made Easy

The DŌS QuietDrive connects to your Apex system via Apex Fusion. The Fusion app dosing wizard makes setup simple, whether you’re configuring basic dosing schedules or automating dosing based on real-time readings from your Trident water analyzer.

Built to Last

With a gearless, direct-drive stepper motor featuring a 5000-hour mean time before failure (MTBF), the DŌS QuietDrive provides unmatched reliability and precision. Expect a lifespan up to 12 times greater than conventional DC motor-driven pumps.

Leakproof, Secure Design

Leakproof fittings are crucial in any dosing system. The DŌS QuietDrive uses sure-fit compression fittings, far superior to the common dual-barbed connectors, ensuring airtight seals and accurate dosing every time.

Engineered with Purpose

More than just a dosing pump, the DŌS QuietDrive is a versatile, high-performance fluid delivery system designed for:

Water Changes

• Variable speed motor: from drops to 30 gallons per day

• Replace large weekly water changes with small, daily, automated exchanges

• Smaller, consistent water changes help maintain aquarium stability

Additives Dosing

Consistent alkalinity and calcium dosing is critical for healthy coral growth. The DŌS QuietDrive delivers additives slowly and uniformly throughout the day to maintain stability.

When paired with a Trident or Trident-NP, it can perform Trident Controlled Dosing — automatically adjusting doses based on your aquarium’s real-time chemistry.

Also Perfect For

• Other additives dosing

• Micro-quantity dosing

• Delivery of liquid foods and supplements
