The Gen 2 changes are significant and certainly worth the wait. The ClariSea Gen 2 is available in two sizes, an SK-3000 capable of 3,000 litres of water per hour, and the SK-5000 for 5000 litres per hour. The two models are virtually identical in their dimensions with the larger SK-5000 being slightly longer – not taller- to increase the surface area of the filter material. A third model is available, an SK3000 without motor. This model is wound on by hand and a motor can be added as an upgrade at a later date if required by the user.   ClariSea SK-3000 The ClariSea fleece filter is a high efficiency water filtration system which effectively removes suspended particles such as micro algae, detritus, food, organic waste and gravel dust from the water column.
