The DOS is a multifunctional dosing and fluid dispensing system. The DOS connects to any Apex via its AquaBus connection. The true versatility and functionality of the DOS comes to life through the software wizards built into Apex Fusion. This takes dosing to a whole new level in terms of ease of use and functionality compared to other stand-alone dosing systems.

The DOS can perform automatic water changes, dose small amounts, and dispense liquid food, among other things.

Required: Apex, Apex Lite, or Apex J.

• 1Link cable
• 4 meters of 6mm tubing
• 50 mL measuring cylinder for calibration

Additional accessories (optional):

• AquaBus cable (if needed for communication with other Neptune devices)
