In practice this matters less than it would on a conventional filter: the sensor detects rising resistance as the fleece loads and advances the roll automatically, rather than requiring the flow to be maintained against an increasingly clogged sock. Ask us for Red Sea's technical documentation if you want to plan sump turnover around a worst-case figure rather than the rated maximum.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cp\u003eSuited to large reef systems up to around 1,200 L with a sump built or modified to accept the unit, particularly heavily stocked SPS and mixed reef displays where sock filtration would need daily attention.
