CLARISEA Paper roll for filter SK3000 XL 40m

CLARISEA Paper Roll for SK3000XL Filter

IMPROVED EFFICIENCY PLUS 50% EXTRA FREE

The ClariSea team spent many months developing a new, more efficient, and long-lasting fleece, which has now been launched under the name ClariSea XL Fleece, with the following benefits:

Increased flow through the media for a longer lifespan

Improvement in dirt removal for cleaner water and darker rollers
Reduced effect on the skimmer foam during the first change of a new roller.
Better water resistance of the central disposable core
Length of the roll: 40 meters - 60% longer than the original 25-meter rolls
Made in Europe
100% recyclable polypropylene

Fleece area on a single roll
Did you know that each Clarisea XL roll has the equivalent surface area of the following number of standard filter socks?

Cost savings

Consider how often you need to change your filter socks!

Do you wash them or change them? If so, what is your value every 3-4 days?

Incredible but true, compare the cost of the two options for yourself and you will understand why the ClariSea fleece filter is so popular.

Micron size

It is not really correct to indicate a micron size for this type of filtering material because it can be misleading.

Like all fleece filters of this type, including bag filters, the size of the particles removed by the media will continuously decrease as the fleece becomes dirtier.

Example: with a 200-micron filter sock, the largest particle that should pass through again is 200 microns, but as the media starts to collect dirt, the holes become clogged, creating increasingly smaller passages, and therefore the bag collects increasingly 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 exactly the same way, except that instead of overflowing and having to change or clean the bag, it automatically rolls to expose a piece of fresh material. The fresh fleece will let larger particles pass through, while the dirtier material will stop the smaller particles.

Flow rate vs filter lifespan

The higher the flow through the fleece, the shorter the roll will last.

Imagine it as a large group of people trying to exit a building through a door. The more they try to leave slowly and in an organized manner, the easier it is for individuals to gather and fill the small gaps in the crowd, much like water and small particles making their way through tiny holes in a fabric.

Compare this to people who try to leave quickly in a panic, creating chaos, causing people to back up around the door, similar to the water level receding and triggering the float to move on the roll in the ClariSea without it being completely saturated with dirt.

This chart is based on the actual flow rate readings measured in a well-stocked reef aquarium.

ClariSea installation height vs filter lifespan

The pressure to force such a significant water flow through such a fine fleece is created by the height of the water column in the ClariSea unit above the water level in the sump.

The greater the difference between the two levels, the higher the back pressure and the easier it is to force the same amount of water through increasingly smaller holes created by the fleece blocks. Therefore, the ideal height would be with the opening of the silencer plates approximately 1-2 cm (1/2-1") below the water surface. (In the "flow vs. filter lifespan" test graph, the bottom of the ClariSea was submerged 11 cm below the surface).

The deeper the Clarisea is in the water, the less head pressure there is to force the water through the fleece, and therefore the shorter the lifespan of the roll.

Autres Factors that affect the lifespan of the filter

The factors affecting the lifespan of the fleece are:

1 - Water flow (volume)

2 - Installation height of the filter above the water.

3 - Dirty tank.

With most aquariums, you will find that they act like large settling chambers where food particles, debris, and dead bacteria settle into the sand or substrate. The clarisea will remove this debris from the water before it has a chance to settle but will also remove sediments from the substrate when it is stirred up by fish or manually.

The rolls in the early days may last longer and should be considered as lasting increasingly longer when the tank is cleaned.

4 - Greedy Fish

Tanks with high loads of hungry fish will dirty the roll faster, but will keep your aquarium sparkling clean by removing uneaten food before it decomposes.

5 - Excessive carbon dosage

Carbon dosing works by growing bacteria in the water column which are then exported out of the system through skimming or filtration. Excessive carbon dosing can lead to bacterial blooms that are perceived as a slight cloudiness in the water. The ClariSea fleece is fine enough to remove these bacteria from the water, but when they are in high volume, it will clog the fleece and reduce its lifespan. If you notice this, we suggest slowly reducing the amount of carbon source being added. Similarly, installing the ClariSea after a nitrate filter will also reduce its lifespan and result in a pale-colored roll due to the white bacteria.
