Red Sea has not published a full head-loss curve for this pump, so treat the 300 L\/h figure as a best-case, zero-head number rather than what reaches your sump in practice.\u003c\/p\u003e\n\u003ch3\u003eSafety\u003c\/h3\u003e\n\u003cp\u003eThe fail-safe logic disables the pump if the sensor disconnects or the pump runs longer than expected, guarding against a stuck-on pump overflowing the sump.
