It drops straight into most 4-inch filter sock chambers and automatically rolls out clean fleece as the old section clogs, pulling suspended waste out of the water and leaving it noticeably clearer. It holds a 25-yard roll of 50-micron fleece and handles up to 750 GPH, so a single roll can run for months instead of days.

As water passes through and the fleece loads up with waste, the water level in the tray starts to rise. When it reaches the magnet-mounted optical sensor, the motor advances a fresh section of fleece, flow returns to normal, the level drops, and the motor shuts off. That cycle repeats on its own until the roll runs out.\u003c\/p\u003e\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #666;padding-left:8px;\"\u003eWhy Reefkeepers Switch\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEasy drop-in installation with no plumbing and no extra sump space needed\u003c\/li\u003e\n\u003cli\u003eFilters to 50 microns, roughly double the filtering capacity of most filter socks\u003c\/li\u003e\n\u003cli\u003ePulls waste out of the water column before it breaks down, which helps hold nutrients down\u003c\/li\u003e\n\u003cli\u003eReplaces the constant every-few-days sock swap with months of hands-off filtration\u003c\/li\u003e\n\u003cli\u003eExpandable to a dual master and slave pair in the same sump if you need more flow\u003c\/li\u003e\n\u003cli\u003eRefilling the roll when it is spent is quick and inexpensive\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"font-size:0.9em;color:#555;\"\u003eHow long a roll lasts depends on bioload, feeding, and flow rate.\u003c\/p\u003e\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #666;padding-left:8px;\"\u003eWhat Is Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eKlir 4 in. drop-in automatic fleece filter\u003c\/li\u003e\n\u003cli\u003e3.9 in. and 4.25 in. swappable collars\u003c\/li\u003e\n\u003cli\u003eV2 Smart Controller and magnet-mount sensor\u003c\/li\u003e\n\u003cli\u003e25-yard roll of 50-micron fleece\u003c\/li\u003e\n\u003cli\u003eActivated carbon insert\u003c\/li\u003e\n\u003cli\u003eDC geared motor (DC 12V \/ 0.6A)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"margin:14px 0 4px;font-size:1.05em;font-weight:600;line-height:1.25;border-left:4px solid #666;padding-left:8px;\"\u003eWill It Fit Your Sump?\u003c\/h3\u003e\u003cp\u003eCheck these four things before you buy.
