Description
When you pair the DOS Fluid Metering System with the DDR Dual Reservoir System you create one of the smartest, state of the art dosing packages in the world. In conjunction with Apex Fusion the ability to make minor adjustments is easier than ever, even allowing you to monitor how much of your favorite liquid 2-part or trace element is left in the DDR Reservoir.
The Neptune DOS Fluid Metering System is one of the smartest dosing pumps on the market. It will hook directly to your existing Neptune Apex, ApexEL, or Apex Jr. giving you the ability to program both pumps independently for what ever kind of dosing your tank may need.
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 calculators out there uses volume. So, with the DOS, DDR, 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 DOS 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.
