ClariSea SK-3000 Gen 3


The Gen3 ClariSea has a number of new features to speed up installation, make it easier to load the fleece, and maintain the unit without having to remove it from the sump or dismantle. The main body now comes fully constructed and glued together, making initial setup of the unit quicker and easier compared with the previous generations.

To aid with periodical cleaning, the guide rollers and splash guard plates can be removed without the need of tools or having to dismantle the unit. The two splash plates are now quick release, using a drop-in slots to make them simple to lift out, even when the unit is installed in a sump. Specially designed thumb screw stub fixings are used to hold the guide rollers, allowing free rotation as the fleece is wound on. This allows easy changing of the fleece without removing the ClariSea from the sump.

The fleece holder has been redesigned to simply drop on to the top of the unit, taking away the need to release or tighten any fixing screws when the roll needs to be removed or replaced. This is especially handy where space is tight or access to the mounting screw would be limited.

All ClariSea Gen 3 units now include a fleece removal tool to help eject the dirty fleece roll from the spool, allowing the dirty roll to be easily pushed off without the need to cut off or unroll the fleece.

Connection to existing aquarium pipework has also been made more versatile with a specially moulded inlet adapter elbow that will fit 32mm metric or 1” Imperial aquarium plumbing as standard or with the use of a 40mm straight connector will also fit directly to 40mm metric pipework.
