The Chihiros Fertilizer Dosing Pump 4 Head is an automatic dosing system designed to deliver aquarium fertilizers and liquid supplements accurately and consistently. With four independent dosing heads, it allows you to automate multiple liquids separately, making it especially useful for planted aquariums that require regular dosing of different nutrients. Chihiros also states that the system is suitable for marine aquariums.
Each of the four dosing channels can be configured independently, allowing different dosing amounts and schedules for each liquid. This makes it convenient for dosing products such as macro nutrients, micro nutrients, iron, liquid carbon or suitable marine supplements without manually measuring them every day. The system supports multiple dosing modes through the Chihiros dosing platform.
The dosing pump works with the MY CHIHIROS App, where dosing schedules and supplement levels can be managed. Its Supplement Volume Monitor can calculate the remaining amount based on scheduled and manual dosing and estimate how many days of supplement are left.
The total daily dose for each head can be set from 0.2ml to 999.9ml, adjustable in 0.1ml increments, while the minimum individual dose is 0.2ml. The four-head model has a specified dosing flow of 50ml/min, providing fast and controlled liquid delivery.
With compact dimensions of just 17.7 × 5.4 × 4.2cm, the Chihiros Fertilizer Dosing Pump 4 Head fits neatly inside or around an aquarium cabinet. Its internal BPT tubing has a rated working lifetime of at least 1000 hours, supporting dependable long-term aquarium dosing.
For aquascapers who want consistent nutrient delivery with less daily manual work, this four-channel dosing system provides a convenient way to automate an aquarium fertilization routine.
