Flexible reef dosing on the Nereus platform
The Nereus Dual-Head Doser is a two-channel reef doser that works with the Nereus platform - the same live dashboard as the reef controller. Set how much you want each day, choose a frequency, and the platform calculates the volume for every dose so alkalinity, calcium, magnesium and other reef supplements land smoothly across the day.
Scheduling that adapts to your tank
- Enter ml per day for each head
- Choose a frequency: every 15 minutes, 30 minutes, or 1 hour
- Nereus automatically calculates how much to dose each interval
- Each head is scheduled separately - alk on one side, calcium (or another supplement) on the other
- Manual dosing anytime from the Nereus platform when you need a one-off addition
Accuracy and calibration
- Dosing accuracy around ±0.5 ml
- Calibrate each head individually so pump output stays true as tubing ages or solutions change
Why reefers automate dosing
Large single dumps swing parameters; many small doses keep chemistry closer to target. With independent schedules, charts on the dashboard, and the same platform login as your controller, dosing becomes measurable - not guesswork.
Built for reef supplements
Pair the doser with Nereus alkalinity, calcium and magnesium reef supplements, and watch totals and trends next to controller data. One brand, one platform, one clear picture of what you dosed and what your reef did next.
