Product details
Neptune Apex DOS Dual Reservoir is a dosing-reservoir accessory designed for aquariums using the Neptune DŌS system. It gives you extra storage volume for liquid additives so your Apex can meter them more conveniently through your dosing lines. In practice, it’s commonly used for two-part solutions such as alkalinity/calcium (Alk/Cal) and for other applications where multiple liquids need reliable level sensing and straightforward refilling.
Features:
- Stores fluids on both sides, with each side holding two liters (2L)
- Connects directly to your DŌS setup for streamlined integration
- Optical sensors inform your APEX when levels are low
- Strong, cast-acrylic construction for durability in aquarium service
- Low-profile design helps it sit securely and resist tipping
- Easy-to-refill reservoir design for quicker maintenance
- Push-fit tubing connections for convenient plumbing
- Suitable for two-part (Alk/Cal), additives and other compatible dosing applications
