Red Sea ReefDose 2 — Smart 2-Head ReefBeat Dosing Pump for Reef Aquariums

The Red Sea ReefDose 2 is a two-head automatic dosing pump built specifically for the daily supplementation of reef aquariums. Each head runs on a direct-drive planetary gear-motor accurate to ±0.05 ml — down to a single drop — and everything is programmed through the ReefBeat app, like the rest of Red Sea's smart devices. The ReefDose is a patented device.

ReefDose 4 accuracy in a compact footprint

Each head handles a daily dose from 0.2 to 1000 ml in 0.1 ml increments, with three flow rates: Whisper at 15 ml/min for near-silent operation, Regular at 30 ml/min and Turbo at 45 ml/min. The unit measures just 13 x 10.5 x 8.5 cm (5.1" x 4.1" x 3.4") and Red Sea rates the motors for a 10-year life expectancy.

ReefBeat does the scheduling for you

• 4 automatic dosing programs: single daily dose, 24 hourly doses, a timer schedule (up to 24 individually set doses per day, per head) or a customized schedule — every day or selected days only.
• Dynamic Dosing Queue: both heads' plans merge into one coordinated schedule, with an automatic delay between heads to prevent chemical interaction between supplements.
• Missed-dose compensation after a power outage, maintenance or feeding.
• Supplement volume monitor with refill notifications.
• Dose log, hour by hour over 30 days, exportable.
• 4-Part dosing calculator that applies its recommendations straight to the doser.
• Food head for liquid food, triggering Feed Mode automatically.
• On-demand manual dosing at any time, plus missed-dose notifications.

Tool-free installation

The heads click on and off without tools. A wall-mounting bracket is included and the secured connectors take flexible tubing of 5 mm outer diameter (3 mm inner).

Our advice

Before settling on the ReefDose 2, think about how many products you'll be dosing a year from now: most reefers end up with three or four supplements, which is why in store we generally recommend the ReefDose 4. The 2 is still the exact same device, with the same accuracy and the same easy ReefBeat programming — we run ReefDose pumps just about everywhere in the shop ourselves.

Complementary products

If you expect to dose more than two products, look at the Red Sea ReefDose 4. The Deluxe 4-color tube kit (Blue/Green) supplies tubing, holder and tips for the hookup. For daily dosing, Reef Energy Plus AB+ works nicely on the Food head, and NO3:PO4-X benefits from steady automated dosing.

Frequently asked questions

ReefDose 2 or ReefDose 4 — which one should I get?

Same accuracy, same app: the difference is the head count and the width (13 cm vs 22.5 cm). The 2 fits when you dose one or two products consistently; as soon as you're aiming at the 4-Part program or several supplements, the 4 saves you a second purchase.

Does the ReefDose 2 need Wi-Fi?

No. Red Sea's official manual provides an "Offline" mode when no network is available at the aquarium; Wi-Fi is still required for remote notifications and full ReefBeat functionality.

Which tubing works with the ReefDose 2?

Red Sea specifies flexible tubing of 5 mm outer diameter and 3 mm inner diameter on the secured connectors. The ReefDose tube kits — with distinct colors to identify each supplement — are made exactly for this format.
