Description
Description
The Chihiros 4-Channel Dosing Pump is an app-controlled automatic fertilizer doser built for planted aquariums and reef tanks. It runs up to four independent dosing heads, each programmable from 0.2 ml to 999.9 ml per day in 0.1 ml increments, delivering liquid fertilizers, trace elements, or calcium/alkalinity supplements on a fixed daily schedule — with no manual dripping, no forgotten doses, and no guesswork.
Why aquascapers switch to it
Manual fertilizing works until it doesn't — a missed Tuesday, an uneven pour, a vacation. The Chihiros pump removes that variability entirely. Each of the four heads doses independently, so you can run a nitrogen-phosphorus-potassium fertilizer on channel one, a micro/trace mix on channel two, and a third product entirely on channel three, all on their own timing — without cross-contaminating bottles or eyeballing capfuls.
- 4 independent channels — separate schedules and volumes per fertilizer or additive
- 0.1 ml precision — fine enough for both nano tanks and large aquascapes
- 30-second stagger between heads — prevents different nutrients reacting inside the tank
- Missed dose compensation — after a power cut, the day's skipped doses are automatically caught up
- CR2032 battery backup — keeps schedule and clock alive through outages (battery sold separately)
- My Chihiros app control — set, adjust, and monitor all four heads from your phone
- Compact footprint — 17.7 × 5.4 × 4.2 cm, mounts easily inside a cabinet or on the rim
Who it's for
Built for hobbyists running high-tech planted tanks on the Estimative Index or lean-dosing method, aquascapers who travel or can't dose at the same time every day, and reef/marine keepers who need separate, precise dosing of calcium, alkalinity, and magnesium. If you're currently pouring fertilizer from a bottle by eye, this is the upgrade that makes your dosing repeatable.

Frequently asked questions
Can the Chihiros 4-Channel Dosing Pump be used for both freshwater and saltwater tanks?
Yes. It's built for both — freshwater planted/aquascape setups (fertilizers, trace elements) and marine/reef tanks (calcium, alkalinity, magnesium, and other supplements), with each of the four channels handled independently.
What's the smallest dose it can deliver?
0.2 ml is the minimum single dose per head, adjustable upward in 0.1 ml increments up to 999.9 ml per day — precise enough for nano tanks and large aquascapes alike.
Do I need a battery for it to work?
The pump runs on mains power without a battery. The CR2032 battery (sold separately) is only needed to keep the internal clock and schedule saved through a power outage, and to enable missed-dose compensation.
Can I dose different fertilizers at the same time without them mixing?
Yes — each of the four heads has its own tube and outlet, and the pump automatically staggers doses by 30 seconds between channels so different nutrients don't react with each other inside the tank.
How is it controlled?
Through the My Chihiros mobile app via Bluetooth. You set frequency and volume per channel independently and can save or adjust schedules at any time.
Pairs well with
Most owners run the pump with a complete liquid fertilizer on one of the channels. 2Hr Aquarist APT 3 – Complete Fertilizer is a natural match: a single all-in-one NPK and micronutrient formula that the pump can dispense automatically, every day, at the exact dose your tank needs — without you touching a bottle.
