The Gen 3 Clarisea SK-3000 incorporates all the changes and improvements of the upgraded Gen 2.1 automatic filter roller, but with a host of new features designed to make your aquarium maintenance even easier! The new model comes with a pre-assembled filter body and quick-release silencer plates for easy assembly and cleaning, as well as a drop-in fleece holder, top rollers to guide the fleece, and a fleece removal tool for seamless operation.


ClariSea fleece filters automatically remove particulates from your water that would normally turn into nitrates and phosphates. Perfect for reef aquariums, the SK-3000 Automatic Filter System will leave your tank with brilliantly clean water which will help increase your lighting penetration, reduce maintenance, and the best benefit of all, let you see your corals and fish with fewer particulates in the way. 

  • High volume filtration capacity
  • Minimal installation footprint
  • Completely replaces the need for filter socks 
  • Multiple installation options 
  • Automatic advance of dirty fleece 
  • Multi-function smart controller
  • End of roll audible alarm
  • Filter jam/float error/water depth alarm
  • Phosphate free fleece material
  • Special low-odor fleece material
  • Integrated fail-safe overflow

*New Features Unique to Gen 3*

  • Pre-assembled body
  • Upgraded motor
  • Quick-release silencer plates
  • Top rollers with fleece guide
  • Drop-in fleece holder
  • Easy cleaning design
  • Fleece removal tool


By allowing the water from your aquariums overflow to drain into the ClariSea, you can trap and effectively remove detritus and other foreign particulates from your water without having to ever change a filter sock again. Utilizing a sensor to know when the fleece is starting to clog, the ClariSea will automatically advance the fleece ahead allowing clean fleece to trap more particulates. Removing the old fleece rolls only takes a minute and will only need to be maintained once every couple of months, which may vary depending on your specific aquarium.

Product Questions

Can you use it in the 7 inch filter stock hole.
Question by: Lester Fuqua on May 11, 2023, 9:23 PM
Unfortunately, this is not designed to fit in a filter sock holder. The only option we carry for a 7" filter sock hole would be SKU 251942.

Does this have 10v or IOTa for using external controller alarms?
Question by: David Gill on Mar 20, 2022, 2:27 PM
Hey David, thanks for reaching out! to my knowledge the Clarisea is only able to use its controller and does not have 0-10V compatibility
