Jebao DP-4 Programmable Aquarium Dosing Pump, Black, 4 Channels

The Jebao DP-4 is a programmable aquarium dosing pump for dispensing supplements and other liquids, with four independently controlled channels and up to 24 dosing times per channel each day.

• Four dosing channels — schedule different liquids independently.
• Up to 24 dosing times per channel per day — automate repeated dosing.
• 1–9,999 mL per channel per day — set dosing amounts in small or large increments.
• Power supply, soft tubing and a four-tube fixture included — supplies the listed pump accessories.
• Six-month manufacturer warranty — covers replacement of parts that fail because of manufacturing errors.

Regular aquarium dosing can mean measuring and adding supplements by hand each day. The DP-4 automates scheduled dispensing to help keep tank parameters stable and remove the need for daily supplement mixing. It is designed for calcium, magnesium, AB water and other liquids, with separate programming for each channel.

How many liquids can the Jebao DP-4 dose?

The Jebao DP-4 doses up to four liquids through four separate channels. Each pump can be programmed individually, so dosing times and amounts can be set for the liquids assigned to each channel. The controller supports dosing up to 24 times a day, and the interval setting supports a 30-day dosing interval.

• Four-channel pump design.
• Q max: 70 L/m.

What liquids and dosing amounts suit the DP-4?

The Jebao DP-4 is intended for calcium, magnesium, AB water or other liquids used for aquarium dosing. Each channel provides 1 to 9,999 mL per day, allowing programming for small or large daily amounts. Automated, individually set dosing is designed to help maintain stable tank parameters without daily manual mixing.

• Each channel has its own programming.
• Daily output range: 1 to 9,999 mL per channel.

What is included, and what setup does the DP-4 need?

The Jebao DP-4 comes with a power supply, soft tubing and a four-tube fixture. Calibrate the pump before use with a 100 mL graduated cylinder or measuring cup; that measuring vessel is not included. Once calibrated, the pump is plug and play. The user manual and guide are available on this page.

• Dimensions: 9.25 x 5.11 x 2.55 in (23.5 x 15 x 6.5 cm).
• Six-month warranty covers replacement of parts that fail due to manufacturing errors.

The DP-4 suits aquarium keepers who want to automate separate liquid dosing schedules, including calcium, magnesium and AB water. It is a four-channel dosing pump that requires calibration with a separate measuring vessel before its first use.
