Chihiros 4-Channel Automatic Dosing Pump System - Complete Set for Planted Aquariums

Chihiros 4-Channel Automatic Dosing Pump System – Complete Set

The Chihiros 4-Channel Dosing Pump Complete Set is a ready-to-install automated fertilizer dosing system for planted and reef aquariums. Unlike the standalone pump, this set bundles everything needed to get running immediately: the 4-head dosing pump, four 450 ml color-coded dosing bottles, a stainless steel bottle holder, a tube organizer, silicone tubing, and a measuring cylinder for calibration.

What Makes It Different

Each of the four channels operates completely independently, controlled entirely through the My Chihiros app — the unit itself has no buttons, which keeps it compact and unobtrusive under a cabinet. Dosing volume is adjustable from 0.2 ml up to 999.9 ml per day in 0.1 ml increments, at a dosing rate of up to 50–60 ml per minute, so it handles everything from a light daily trace-element dose to heavier macro fertilization.

The system staggers each channel's dose by 30 seconds, which prevents different fertilizers from meeting and reacting inside the tubing or at the outlet. A built-in "Supplement Volume Monitor" tracks how much liquid remains in each bottle based on your dosing schedule and warns you in the app roughly three days before a bottle runs dry — no more discovering an empty bottle mid-week.

Key Benefits

• Complete kit: pump, 4× 450 ml color-coded bottles, stainless steel holder, tube organizer, tubing, and measuring cylinder
• Four fully independent channels, each dosing 0.2–999.9 ml daily in 0.1 ml increments
• 30-second stagger between channels prevents fertilizer interactions
• Supplement Volume Monitor tracks remaining liquid and warns before it runs out
• Missed-dose compensation with CR2032 battery backup keeps schedules on track through power outages
• Suitable for both freshwater planted tanks and reef/saltwater systems

Who Should Use This

• Planted tank keepers dosing multiple liquid fertilizers who want to stop measuring and pouring by hand
• Reef and saltwater aquarists dosing calcium, alkalinity, magnesium, or trace elements
• Anyone who travels frequently or wants reliable dosing without daily manual intervention
• Aquarists setting up dosing for the first time who want a complete kit rather than sourcing bottles and tubing separately

Setup and Calibration

1. Mount the pump unit in a dry, accessible location near the aquarium, using the integrated wall bracket if needed
2. Connect the silicone tubing from each pump channel to its corresponding dosing bottle and to the tank
3. Secure tubing along the aquarium rim using the included tube holders
4. Download the My Chihiros app and connect to the pump via Bluetooth
5. Calibrate each channel using the included measuring cylinder — the app walks you through dispensing a test volume and confirming the actual measured amount
6. Set your daily dose, schedule type (single dose, hourly, custom periods, or timer), and let the Supplement Volume Monitor track usage from there

Expert Tip

Recalibrate each channel every few months, or any time you switch to a different liquid — viscosity differences between products (a thick trace-element mix versus a thin water conditioner, for example) can shift the actual dosed volume even with identical settings. A two-minute recalibration with the included measuring cylinder keeps your dosing accurate over time.

Frequently Asked Questions

What's included in the Complete Set that isn't in the standalone pump?

The Complete Set adds four 450 ml color-coded dosing bottles, a stainless steel bottle holder, a tube organizer, tubing, and a measuring cylinder — everything needed for a full working setup out of the box.

Can I use this for a reef or saltwater tank?

Yes, it's suitable for dosing calcium, alkalinity, magnesium, and trace elements in reef systems, as well as liquid fertilizers in freshwater planted tanks.

Does it need a battery to work?

The pump operates on mains power without a battery, but a CR2032 battery (not included) is recommended so the clock and schedule are retained during power outages, with missed-dose compensation.

How precise is the dosing?

Dosing is adjustable in 0.1 ml increments, from 0.2 ml up to 999.9 ml per day per channel.

Do I need to calibrate before first use?

Yes — calibration with the included measuring cylinder ensures the dosed volume matches what you set in the app, since pump output can vary slightly by unit and by liquid type.
