ClariSea Replacement XL Fleece are not only efficient, but will save you money in the long run. Do you know that on each Clarisea XL roll there is the equivalent surface area of the following number of standard filter socks:

SK5000 XL - 115 x 4" Filter socks.
SK3000 XL - 75 x 4" Filter Socks.

Other Key Features and Benefits include:
  • Increased flow through the media for longer life.
  • Improved dirt removal for cleaner water and darker rolls.
  • Reduced effect on skimmer foam when first changing a new roll.
  • Improved water resistance of centre disposable core.
  • 40m roll length - 60% longer than the original 25m rolls.
  • Made in Europe.
  • 100% recyclable polypropylene.

Micron Size: It is not really correct to state a micron size for this type of filter material as it can lead to confusion. Like all fleece filters of this type, including bag filters, the size of the particle removed by the media will continuously reduce as the fleece dirties.

Example; with a 200 micron filter sock, the largest particle that should pass through when new is 200 microns, however as the media starts to collect dirt, the holes get blocked creating smaller and smaller passages and so the bag collects out smaller and smaller particles. It continues to do this until the head pressure can no longer force water through the small holes and it overflows.
The ClariSea works in exactly the same way except that instead of overflowing and having to change or clean the bag, it automatically rolls on to expose a fresh piece of material. The fresh fleece will allow larger particles to pass through and the dirtier material will stop smaller particles.

ClariSea Installation Height vs Filter Life: The pressure to force such a large flow rate of water through such a fine fleece is created by the head height of the water in the ClariSea unit above the water level in the sump.

The higher this difference is between the two levels, the higher the head pressure, and the easier it is to force the same amount of water through smaller and smaller holes created as the fleece blocks. The perfect height would therefore be with the opening to the silencing plates being about 1-2 cm (1/2-1") below the water surface. (On the tests for the 'flow vs filter life' chart, the bottom of the ClariSea was submerged 11cm below the surface).

The deeper the Clarisea sits in the water, the less head pressure exists to force water through the fleece and therefore the shorter the life of the roll.
