PetPal Gear Score

Synthesized from manufacturer specifications (Reef Octopus / CoralVue, Sicce, Current USA, Jebao) and reef-keeping education from Bulk Reef Supply, weighted by field reputation for longevity, warranty length, motor and impeller durability, and parts availability. A return pump runs continuously for years, so a proven platform earns more here than a feature list. The Return Pump Score is a composite of published specs and expert consensus, not a measurement — PetPalHQ does not run a testing lab.

How well the pump delivers usable turnover after head loss, not just its open-flow rating. We weight rated max flow against the max head height, because vertical lift and elbows reduce effective GPH, and we credit pumps that keep real-world flow in the 5-10x sump-turnover band on a typical stand. Head reserve matters as much as headline flow, which is why the lowest-head pick is penalized here even when its rated flow is competitive.

How precisely flow can be set and integrated into a wider system: adjustable DC speed ranges, feed/pause modes, 0-10V or app control, and third-party controller compatibility such as a Neptune APEX. Fixed-speed AC pumps that throttle only with a gate valve score lower here by design, which is a deliberate trade against their reliability strength rather than a flaw.

Operating noise and ongoing power draw on a device that never turns off. We read this from manufacturer power-consumption figures and motor design — DC pumps and sine-wave or synchronous-motor AC pumps that run quietly and sip power earn credit, while higher-draw or noisier units lose points. Efficiency here is an operating-cost and livability factor, not a purchase-price factor; price is intentionally not weighted in this score.
