Red Sea ReefDose Measuring Cylinder
Confirm every dose is exactly what the app says it is. The Red Sea ReefDose Measuring Cylinder is the calibration accessory for ReefDose dosing pumps — a small graduated glass cylinder that lets you catch and check a single dose against what was scheduled.
Key features
- Glass construction, 5 mL capacity
- 0.1 mL graduations for precise small-volume reading
- Fast, repeatable manual calibration checks
Will this fit my ReefDose?
Yes — it's a universal accessory for the ReefDose range, not tied to a specific channel or model. It works the same way on a ReefDose 2 or a ReefDose 4.

Suitable for, and not suitable for
Suitable for calibrating any ReefDose head, and for spot-checking dose accuracy after fitting a new head tube or gear motor. Not a replacement part in itself — it doesn't fix a dosing fault, it tells you whether one exists.
Care and maintenance
Rinse with fresh water after each use, especially after measuring alkalinity or calcium supplements, and dry before storing to avoid crystalline residue clouding the graduations.
Warranty and delivery
Covered by Red Sea's standard spare parts warranty against manufacturing defects, in addition to your rights under Australian Consumer Law. Standard parcel delivery. Glass item — handle with care in transit.
Common questions
How do I calibrate a ReefDose head with this?
Run a manual dose from the app into the cylinder, then compare the measured volume against the volume the app expected, and adjust the calibration setting to match.
Does one cylinder cover all four channels on a ReefDose 4?
Yes — calibrate each head in turn with the same cylinder.
Is it fragile?
It's glass, so treat it as you would any lab glassware — it isn't shatterproof.
