About This Used Doser

Brand New DOS Heads Included
Clean & In Great Working Condition

Please Note: This doser requires an apex system to work.

The Neptune DOS is a multi-purpose Dosing and Fluid Metering System. The DOS connects to any Apex via its AquaBus connection. The true versatility and functionality of the DOS comes to life via the software wizards built into Apex Fusion. This takes dosing to a whole new level in terms of ease of use as well as functionality when compared to standalone dosing systems because the DOS is part of your Apex ecosystem. Not only can you integrate it into other operations and devices you have configured, but we also will be continuing to expand on its capabilities as time goes on via software updates to Apex Fusion.

Features:

2-part dosing (Calcium and Alkalinity)
Other additives dosing
Automatic water changes
Micro-quantity dosing
Delivery of liquid foods and supplements

The #1 reason people purchase a dosing system for their aquariums is for consistent and easy dosing of 2-part solutions (calcium and alkalinity) to their reef tanks. The most common method for doing this today is to use standalone dosing pumps and run them on a timer using seconds or minutes to determine how much to dose. This is not only confusing, but also prone to inaccuracy. Everyone knows that when measuring a fluid it is done by volume, not time. Every dosing calculator out there uses volume. So, with the DŌS (and the Apex Fusion interface) you simply enter the amount you want of each part of the additives (one on each pump) and what hours of the day you want it delivered. The DŌS then sets up all the dosing intervals within that time period. When that time interval is finished, the exact volume you set has been delivered. It even automatically chooses the slowest speed necessary for the pump so that it minimizes noise.

Automated Water Changes
Water changes with the DOS is super easy. With the DOS all you do is place your empty vessel and your fresh stock of saltwater under your stand. Then, with the Apex Fusion wizard just tell it amount of water you want to change over what length of time and the hours of the day you want it to happen and it figures it all out for you. It will perform an automatic, continuous water change for you. It gets better. If you have our dual optical water sensing accessory Apex Fusion will send you an email or text message letting you know it is time to change out the jugs. Less time pumping, siphoning, and sloshing water and more time enjoying a great aquarium.

Micro-Dosing Of Elements
If you need to dose tiny amounts of a particular solution, element or other fluid (like vodka dosing or 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 all the way down to 0.1ml at a time!

Larger Diameter & Secure Tubing Connections
Larger size tubing means that your pump does not have to work nearly as hard – or stay on for longer cycles. The most popular dosing pumps on the market use tube fittings with the tiny diameter of 1.67mm. The DOS uses much larger tubing and fittings. In fact, at 3.33mm in diameter, the pump on the DOS can handle 4x the flow of the most common pump style on the market. This means that your pump (and motor) will run 1/4 the time to pump the same amount of fluid. Less run time means less wear on the pump.

Simplified Interface
The DOS has an accessory port that enables it to be connected to an optional accessory like the DDR – Dual DŌS Reservoir. This accessory has two separate 2-liter cylinders for holding your additives. It also has optical sensors at the bottom that tell the Apex when it is time to refill and it then can send you an email or text alert.

Silent Operation
The Neptune Systems engineering team have taken extensive steps both in how the pump operates as well as the enclosure design to ensure that the DOS system is one of (if not) the quietest dosing systems on the market for the fluid volumes it delivers.
