Jebao DP-4 Programmable Dosing Pump
The Jebao DP-4 is a four-channel dosing pump designed for flexible additive delivery. Each channel can dispense between 1 and 9999 ml per day, enabling hobbyists to split dosing across calcium, magnesium, alkalinity solutions, and other liquids. With a built-in 24-timer-per-day feature, you can schedule multiple dosing events across the day, providing steady parameter control without constant manual dosing. The four independent channels make it possible to run different liquids in parallel, which is especially useful for reef tanks that require coordinated two-part dosing or separate trace element regimens.
In practice, the DP-4 supports a modular dosing approach: assign channels to individual solutions, calibrate each line for accuracy, and align dosing times with checks for evaporation and water changes. The unit’s peristaltic design means tubing wear is a normal part of routine maintenance; plan for periodic tubing replacement to preserve accuracy. For larger tanks or systems with multiple dosing targets, the DP-4 reduces the need for several single-channel pumps, saving space and simplifying wiring behind the sump or cabinet.
Setup emphasizes reliable repeatability. After installation, test the channels with a controlled calibration to confirm ml-per-day outputs align with intended doses. The 24-hour programming supports step-down or step-up dosing patterns to match feeding schedules and light cycles. While the DP-4 handles many additives, keep compatibility in mind: check that liquids are suitable for peristaltic dosing and that containers, tubing, and adapters are aligned with your tank’s chemistry goals.
Kamoer KCP-X Mini Peristaltic Pump
The KCP-X Mini is a compact, 24V peristaltic pump designed for precise low-flow dosing. Its flow rate ranges from 19 to 65 ml per minute, making it suitable for maintaining trace elements, amino acids, or small-volume additives in nano or pico reef tanks and experimental setups. A notable feature is the ability to adjust the flow by rotating a control knob, with a compact footprint that fits neatly inside cabinet space. The pump head direction can be rotated, and compatible heads and tubing are offered for customization and replacement, expanding its versatility over time.
Users often appreciate the KCP-X for its straightforward setup and stable operation. With a lightweight design (about 185 g excluding the power supply) and a included power source, it delivers reliable dosing without adding unnecessary bulk. The device’s focus on low-noise operation makes it well-suited for quiet living rooms or offices where the aquarium is visible and audible—all while maintaining precise, repeatable deliveries across multiple liquids.
For maintenance, the KCP-X emphasizes easy tubing changes and head replacements. The adjustable flow range supports a variety of tank sizes, from small reefs to larger freshwater systems that require careful control of nutrient dosing. When integrating this pump, plan to verify tubing compatibility and perform regular calibrations to ensure that each channel maintains the intended volumes for consistent water chemistry management.
AC Infinity Peristaltic Dosing Pump
The AC Infinity dosing pump is designed for precise distribution of liquids with a 10-level control system, delivering 21 to 210 ml per minute. It uses a peristaltic roller pump driven by a DC motor, which keeps output steady while minimizing noise and energy use. This pump shines in applications where accurate, repeatable dosing matters, such as pH-control regimens, reef supplementation protocols, or hydroponic nutrient delivery. The ten discrete settings let you dial in exact flow increments to match tank size and consumption rates.
In practice, the large flow range supports both small tanks needing slow dosing and larger setups requiring faster addition during routine maintenance windows. The motor design emphasizes efficiency and longevity, reducing wear and tear on tubing over time. The device is well suited to environments where dosing must be integrated with monitoring equipment, and it tolerates a range of reagents commonly used in aquariums and labs.
Maintenance involves regular tubing inspection and replacement, as polyether blocks can wear with continuous use. Calibrate flows to account for any tubing stretch or temperature-related changes. The unit’s robust construction helps resist moisture and splash near the sump, but the tubing and fittings should still be checked frequently to prevent leaks or mis-dosing during critical dosing windows.
Kamoer M1-STP Intelligent Dosing Pump
The M1-STP is an intelligent peristaltic pump designed for laboratory and aquarium dosing with a 24V motor and a long-life stepper drive. It features a color LCD screen (1.8 inches) for easy on-device programming and monitoring. The pump delivers 0 to 88 ml per minute with a low noise profile (about 47 dB), making it suitable for quiet homes and offices. Multiple operation modes—time, volume, continuous, and cycle dosing—provide flexible dosing strategies for reef tanks and lab experiments.
This model emphasizes user control and precision. Start/stop, speed regulation, and calibration are supported, and the device can be integrated into more complex automation systems. The compact footprint and adjustable head orientation add practical versatility, especially for mounting in tight sump spaces or on a lab bench. Users should regularly calibrate and validate dosing accuracy, and keep an eye on tubing wear as with other peristaltic pumps.
In application, the M1-STP is well suited for nano and larger tanks that require careful micro-dosing, as well as for experimental dosing schedules where repeatability and traceability matter. The built-in display helps operators monitor dose rates without relying solely on external controllers, simplifying routine checks and reducing setup time for automated dosing routines.
Chihiros Reef Dosing Pump
The Chihiros dosing pump is tailored for reef aquariums, with a focus on precision dosing of reef supplements and water treatments. It’s designed for versatile compatibility with dosing containers, vessels, and adapters, enabling a seamless fit into various dosing setups. The pump is marketed as low-maintenance and durable, helping to minimize downtime in reef maintenance routines while delivering consistent doses essential for coral health and stability of alkalinity, calcium, and magnesium levels.
While the exact flow range isn’t listed in the included features, the CHIHIROS unit emphasizes accuracy and ease of use in demanding reef environments. The design aims to reduce clutter behind the sump with straightforward tubing connections and robust construction. For reef keepers, this pump can be a reliable option for routine dosing tasks, water treatments, and targeted additive delivery, provided you verify compatibility with your dosing containers and perform periodic calibration checks.
Buying Guide
Key Factors To Consider
- Flow range and channel count: Larger tanks typically benefit from higher flow rates and multiple channels to dose different liquids without cross-contamination.
- Control options: Look for timers, volume-based dosing, or intelligent modes. LCD displays and on-device controls simplify setup and monitoring.
- Size and noise: Compact units fit tight sump spaces, while quieter models are preferable for living spaces or offices.
- Tubing compatibility and maintenance: Peristaltic pumps rely on tubing; plan for regular replacements and ensure tubing sizes match your liquids and containers.
- Power and reliability: A stable DC motor and robust construction reduce drift and downtime, especially in automated setups.
- Application fit: Reef tanks often require precise dosing of calcium, alkalinity, and magnesium, while freshwater tanks may need different additives; choose a pump whose flow and control align with your chemical regimen.
- Safety and dosing accuracy: Consider devices with clear calibration procedures and mechanisms to prevent overdosing or mis-dose events.
How To Choose For Your Setup
Start by assessing tank size and planned additives. For nano tanks, a compact pump with 19-65 ml/min or 0-88 ml/min capability may suffice, while larger systems benefit from higher flow options like the 21-210 ml/min range. If you plan to dose multiple liquids, a four-channel device such as the DP-4 enables simultaneous, isolated dosing without swapping lines.
Consider control complexity. If you prefer simple on-device scheduling, prioritize units with multiple timers and easy calibration. For lab-like precision, select models with LCD displays and multiple operation modes (time, volume, continuous, cycle). Finally, factor in maintenance: tubing life, ease of head replacement, and the availability of compatible heads or adapters will influence long-term reliability and cost of ownership.
