The Neptune Systems DOS Dosing System is a multi-purpose dosing unit with 2 channels for very precise dosing from 0.1ml. 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.

A multi-purpose dosing and fluid delivery system of uncompromising quality combined with the simplicity of Apex Fusion software wizards for operations such as:

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

DOS Dual Reservoir

The DOS Dual Reservoir (DDR) is an attractive fluid containment system that stores your dosing fluids in style and even tells you when it's time to refill. Each side of the reservoir stores two liters of fluid and can be directly connected to your DOS system. The optical sensors inform your APEX when levels are low. The reservoirs are a strong, cast-acrylic construction and easy to refill. The DOS Dual Reservoir won't easily tip over because of the low-profile design.
