Aquarium Choice Dosing Container Reservoir - Triple 4.5L Storage

In this review the Aquarium Choice dosing container is assessed as a practical reservoir for reef keepers who dose multiple microelements. The unit's single biggest selling point is its three separate acrylic storage sections that keep dosing liquids organized and sealed, making it a good fit for hobbyists running multiple dosing lines. The review looks at build, capacity, and real-world handling so you can decide if this reservoir fits your dosing setup.

Key Features

• Triple compartments: Three separate acrylic storage sections allow tidy separation of additives so users can run distinct dosing schedules without mixing solutions.
• Large total capacity: Each reservoir holds 1500 ml for a combined 4500 ml, offering extended intervals between refills for small to medium tanks.
• Compact footprint: At 31.8 cm x 10.8 cm x 17.5 cm the container fits into crowded sump or cabinet spaces where larger reservoirs would not.
• Color-coded lids and scales: Red, green, and blue lids with visible capacity scales make it easier to identify contents and monitor levels at a glance.
• Included tubing: The package includes three 1 m white silicone dosing tubing runs so the reservoir is ready to connect to dosing pumps without sourcing extra lines.
• Evaporation control: Each section has a lid designed to reduce liquid evaporation and keep contents more stable over time.

Who It's For

The Aquarium Choice dosing reservoir is best for reef hobbyists and freshwater aquarists who need to dose two to three different additives reliably and want a compact solution that fits in limited spaces. Its 4500 ml total capacity suits weekly to monthly top-up schedules depending on dosing volumes and dosing pump settings.

Those who require airtight, long-term storage for oxidation-sensitive reagents or who run very long tube runs where prime retention is critical may want to consider higher-end reservoirs or systems with dedicated airtight fittings, since some users report air leakage and prime issues in the lines.

Pros & Cons

Pros

• Clear, separate chambers make mixing and identifying dosing liquids straightforward.
• Good total capacity for a compact reservoir, reducing refill frequency for many setups.
• Color-coded lids and capacity scales improve usability and reduce dosing mistakes.
• Supplied silicone tubing gets the reservoir connected to pumps immediately.

Cons

• Some customers report air leakage and trouble keeping lines primed, so expect to check fittings and taps after installation.
• Threaded taps on a few reports can be a weak point for long-term airtight performance.

Our Verdict

For hobbyists who need a compact, organized dosing reservoir, the Aquarium Choice three-chamber container is good value and practical for small to medium tanks. It keeps three additives separated, offers ample combined capacity, and comes ready with tubing. Buyers should be mindful to inspect and test fittings for air leakage and prime retention when first installing.

Frequently Asked Questions

Does the unit come with tubing?
Yes, it includes three 1 m lengths of white silicone dosing tubing to connect each chamber to dosing pumps.

What is the capacity of each chamber?
Each separate reservoir section holds 1500 ml, for a 4500 ml total capacity.

Are the lids airtight?
The lids reduce evaporation and seal the chambers, but some users report air leakage at threaded taps, so check fittings during setup.
