Gear Score Methodology
PetPal Gear Score
Best Reef Dosing Pumps (2026)
Editorial synthesis of manufacturer and retailer specifications consulted directly (CoralVue and Premium Aquatics for Kamoer; Chihiros Aquatic Studio, Glass Aqua, and Buce Plant for Chihiros) and aquarium-education sources, with each spec quoted from the page it came from — no first-hand product testing. The Dosing Precision Score is a composite of published specs and expert/hobbyist consensus, not a measurement; PetPalHQ does not run a testing lab. Rank reflects best-fit use case (single-channel all-rounder, budget precision, multi-channel system, high-flow premium), NOT raw score order — a higher-ranked pick is the better fit for its scenario, not necessarily the higher precision score. Price is deliberately NOT a scoring factor, so the $800-plus high-flow pick is neither rewarded nor penalized on the rubric for its cost; the price caveat is handled in its cons, verdict, and the skip-it section instead.
Dosing Precision Score = (Dose Accuracy & Resolution × 0.35) + (Control & Scheduling × 0.25) + (Reliability & Build Quality × 0.20) + (Ease of Setup & Calibration × 0.20)Factor breakdown
Dose Accuracy & Resolution
35%The core dimension for a doser: how precisely and repeatably it delivers a small dose, including stated accuracy (for example, Kamoer's +/-2% rating), the smallest dose and increment it can hit (Chihiros lists 0.2ml in 0.1ml steps), and how well that suits reef chemistry that drifts on small daily amounts. This is the highest-weighted factor because an inaccurate doser swings alkalinity and calcium, which is exactly what you bought the pump to prevent. The Dosing Precision Score is a composite of manufacturer specs and expert consensus, not a measurement — PetPalHQ does not run a testing lab.
Control & Scheduling
25%How flexibly you can program and spread doses: WiFi or app control, the ability to split a daily dose into many small shots, independent per-channel schedules on multi-head systems, and low-liquid or missed-dose alerts. Spreading a dose across the day is gentler on reef chemistry than one large slug, so scheduling depth is a distinct dimension from raw accuracy.
Reliability & Build Quality
20%Long-term durability and materials: stepper-motor and pump-head longevity, continuous-duty rating where relevant, and the rated life of the PharMed or BPT tubing that is the main wear item. Marine dosing runs unattended for months, so build quality and a known tube-replacement interval matter as a separate dimension from the dosing math.
Ease of Setup & Calibration
20%How straightforward the pump is to install, calibrate, and live with: app setup, calibration against a measuring cylinder, whether containers and tubing are included, and the clarity of the controls. Price is deliberately excluded from the rubric — these scores reflect precision, control, build, and usability only, never cost, so the high-flow premium pick is neither rewarded nor penalized on the score for its price.
