DDR DOS Dual Reservoir

Neptune Systems DDR – DOS Dual Reservoir The DDR is a dual-reservoir storage system engineered for Neptune DOS dosing setups. With two 2-litre chambers, integrated optical level sensors, and a low-centre-of-gravity design, it delivers reliable liquid management for two-part and additive dosing. Built-in sensors transmit real-time volume data to Apex Fusion, triggering low-fluid alerts to prevent dry runs. The cast-acrylic construction features removable lids for straightforward refills and push-fit connectors for secure tubing connections. Compact and stable, the DDR simplifies reef maintenance while keeping your dosing system organised and monitored. Requires Neptune DOS and Apex Controller (A2 or A3 Series) for full sensor integration.
