ClariSea SK-3000 Gen 3

The SK-3000 Gen 3 is an automatic fleece roller for marine and freshwater aquarium sumps, including coral propagation and fish-breeding systems. The fleece catches suspended debris such as uneaten food, detritus, and fine gravel dust. As the fleece loads up and the water level rises, the controller advances a clean section. It can replace filter socks and fits sumps with limited space.

Gen 3 Features

• The preassembled body and multi-size inlet adapter simplify installation.
• Guided top rollers and a drop-in holder make the fleece easier to load. The included removal tool helps take off the used roll.
• Quick-release silencer plates reduce operating noise and provide access for cleaning.
• An integrated overflow and a water bypass provide alternate flow paths.
• The smart controller advances the fleece automatically and gives visual and audible alerts for issues such as a jam, a possible end of roll, or an installation problem.

Smart Controller

Hold Play to advance the fleece manually. A steady blue light indicates standby, and a flashing blue light indicates the motor is running.

The controller alerts you when the roll cannot advance, the float stays up for more than five seconds, or the float has gone too long without triggering. Press Alarm for 1–2 seconds to mute the sound. Automatic advance stays paused while the alarm is active, and manual advance remains available. After checking the cause, hold Alarm for 5–7 seconds to reset the controller.

Optional Clean Roll Positioning Kit

The optional kit lets you reposition the clean roll to fit tighter cabinets or raise it above splashing when the filter sits low in the sump.

Suggested Replacement Fleece

Keep a spare ClariSea SK-3000 4-inch XL QuickChange fleece roll on hand for your next roll change.
