As a working rule for centrifugal pumps generally, flow falls off faster in the second half of the head range than the first — so a typical 1–1.2 m sump-to-display lift with elbows and a check valve will deliver noticeably less than the 13,000 L\/h headline, but comfortably more than half of it.

Fluval's published 100 W and 13,000 L\/h figures are from the US (120 V\/60 Hz) spec sheet — actual power draw and flow on our 50 Hz supply can differ slightly, and Fluval's Australian distributor lists a nearby figure of 12,300 L\/h for the same model. Treat 12,000–13,000 L\/h as the realistic zero-head range on local mains rather than a single fixed number.\u003c\/p\u003e\u003ch3\u003eWill it fit my system?\u003c\/h3\u003e\u003cp\u003eCheck your sump-to-display lift (head height) against the 3.7 m maximum, then subtract for every 90° elbow, check valve and length of narrow-bore hose in the run — each adds friction loss on top of straight-line lift. For most home systems with a 1–1.5 m lift and reasonable plumbing, this pump comfortably clears large tanks; for taller lifts or long plumbing runs, confirm your real-world flow need before buying rather than sizing off 13,000 L\/h.\u003c\/p\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSuitable for: sump return duty on large marine or freshwater systems, dry or submerged mounting, continuous 24\/7 operation.\u003c\/li\u003e\n\u003cli\u003eNot suitable for: small nano tanks (it's oversized and wastes power), or as an inline wavemaker — this is a return pump, not a circulation pump.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eStrip and rinse the impeller and magnet housing every 4–6 weeks to clear salt creep and biofilm, which is the main cause of reduced flow over time.
