Neptune DOS QD Dosing Pump

What It Is

The Neptune Systems DOS QD is a two-channel dosing and fluid-transfer system controlled through Apex Fusion. Use it for aquarium supplements or configure both heads for automatic water changes.

Requires a compatible A2 or A3 Series Apex controller. It does not operate independently.

Why We Like It

It brings dosing into the same Apex system you use to monitor your aquarium. Two independent heads suit calcium and alkalinity dosing, or water changes with one removing old water and the other adding freshly mixed saltwater.

The QuietDrive version reduces operating noise compared with the original DOS, particularly useful when dosing equipment runs in a living space.
