"Smart" aquarium dosing-fluid container alerts you via text or email when it's time to refill. The Neptune Systems DDR DOS Dual Reservoir connects to your Neptune Systems AquaController Apex or Neptune Systems AquaController Apex Jr enabled Neptune Systems DOS Dosing and Fluid Metering System for a highly functional and interconnected dosing system.

Stylishly designed cast-acrylic dosing-fluid reservoir features optical sensors that detect fluid levels and alerts you when remaining fluid is down to approximately 20%. Configure to send you a text or an email, or even trigger other events on your Apex enabled ecosystem. Interface directly into your Apex Fusion dashboard and monitor fluid levels in real-time on your smart phone, tablet, or computer from anywhere in the world.

The Neptune Systems DDR DOS Dual Reservoir is an attractive fluid containment system that stores your dosing fluids in style and even tells you when it's time to refill!

• Optical sensors inform your APEX when levels are low
• Strong, cast-acrylic construction
• Low-profile - won't easily tip over
• Easy to refill
• Push-fit tubing connections
• Use for 2-part (alkalinity and calcium) solutions, additives and other applications
• Includes 4m of DOS tubing

Specifications
Size (Approx.): 10.5" x 8.5" x 5.5"
Fluid Capacity (Approx.): 2000ml (2L) per side
Weight (Approx.): 2 pounds
Requires: Apex, Apex Lite, or Apex Jr. and DOS to operate sensors

NOTE: Use only with fluids compatible with acrylic. Not to be used with solvents and other fluids that may be reactive with acrylic such as methanol. If you are in doubt, please contact the manufacturer of the fluid to see if it will react to acrylic.

Style Meets Function, Deceiving Capacity, No-tip Design
The DDR has great style and will stand out in anyone's equipment room. But it's not just about style. It may not look like it, but each side of the reservoir holds an ample two liters (2000 mL) of fluid. For most saltwater aquariums that are dosing Calcium and Alkalinity to their aquariums, this amount is more than enough to last at least two weeks. If you were dosing other additives, it might last months before needing a refill.

Speaking of refills, the DDR has easy lift off lids that make refilling super easy.

The DDR was also designed to have a low center of gravity. This means, unlike other reservoirs on the market, it is very difficult to inadvertently tip over and ruin your day.

Optical Sensors Alert You When It's Time to Refill
The DDR is the only dosing container on the market that connects electrically to your DOS and uses optical sensors that alert you when your fluid has approximately 20% remaining. This alert could be used to send you a text or an email, or even trigger other events on your Apex. Also, when detecting water level, optical sensors are far less likely to fail than their float switch counterparts.

Connect Directly to your DOS
One simple connection links the DDR to the DOS. No worries about fooling around with loose wires, float switches, etc. Just plug it in and it will show up in your Apex Fusion Dashboard.

Ready for Apex Fusion
Although not required, the DDR interfaces directly into your Apex Fusion dashboard. See in real-time your fluid levels and get an alarm when a reservoir runs low.
