ClariSea Replacement XL Fleece Roll for SK-3000 Filter - D-D The Aquarium Solution


Item #: DD1037

In Stock

ClariSea SK3000XL Replacement Fleece


The new XL means more filter fleece for your ClariSea SK-3000 Fleece Filter Roller; extending the time between changing rolls.

The ClariSea team have spent many months working to develop a new more efficient long life fleece and this has now been released as the ClariSea XL Fleece, with the following benefits;

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

Area of Fleece on a Single Roll

Do you know that on each Clarisea XL roll there is the equivalent surface area of the following number of standard filter socks.

SK3000 XL - 75 x 4" Filter Socks 

SK5000 XL - 115 x 4" Filter socks

Cost Savings

Think how often you need to change your filter socks! 

Do you wash them or change them, if so what is your time worth every 3-4 days? 

Incredible but true, compare the cost of both options to yourself and you will realise why the ClariSea Fleece Filter is so popular. 

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. 

Flow Rate vs Filter Life

The higher the flow rate through the fleece, the less time the roll will last.
Imagine it as a large group of people trying to leave a building through one door. The slower and more organised they try to leave, the easier it is for individuals to bunch together and to fill into small gaps in the crowd, like water and small particles finding their way through small holes in the fleece. 

Compare this with people trying to leave quickly in a panic, and chaos is created, so that people back up around the door, like the water level backing up and triggering the float to move on the roll in the ClariSea without it becoming fully saturated with dirt.

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. 

Other Factors that Affect Filter Life

Factors affecting the life of the fleece are:

1 - Water flow (volume) 

2 - Filter installation height above the water. 

3 - Dirty tank. 

With most aquariums you will find that they act as large settlement chambers and that particles of food, detritus and dead bacteria settle within the sand or substrate. The clarisea will remove this detritus from the water before it gets a chance to settle but will also remove sediments from the substrate as it is stirred up by fish or manually.  

The rolls in the early days may last for a shorter length of time and should be seen to last longer and longer as the tank is cleaned. 

4 - Greedy fish 

Tanks with high stocking loads of hungry fish will dirty the roll faster but keep your aquarium sparklingly clean whilst removing uneaten food before it breaks down. 

5 - Excessive Carbon Dosing 

Carbon dosing works by growing bacteria in the water column that are then exported out of the system by skimming or filtration. Excessive carbon dosing can result in bacterial blooms which are seen as a slight cloudiness of the water. The ClariSea fleece is fine enough to remove these bacteria from the water but when in high volumes will blind the fleece and reduce it`s life. If you notice this then we suggest slowly reducing the amount of carbon source added. Equally the installation of the ClariSea after a Nitrate Filter will also reduce the life and give a pale coloured roll from the white bacteria.

Clear AF!

Pros: Cleans water better than Sox!

Cons: Doesn’t last forever! Needs replacing.

I always have 1-2 replacement rolls on hand. Getting the clarisea was one of the best decisions I made! Rolls last about 6 weeks.

Great Idea

Pros: Works great, Gets dirt out of the water, Stops phosphate farms when pads are left in to long dirty.

Cons: Not the easiest to change a roll out but you don't have to do it that often.

I started using this because I was continuously cleaning filter pads. and getting a lot of debris past the pads. Since I started using this product I can relax on cleaning out the pads every few days to now I replace a roll every several weeks. MAkes life easier

Filters well; filter change a real chore

Pros: Great filtration; always fresh paper presented to the water

Cons: Glue holding paper to roll is too weak. This makes replacing very difficult.

This filter filters water really well. It keep the water crystal clear. But it has one big flaw; the filter change is difficult. The manufacturer's video recommends stapling the end of the new filter to the last bit of the old filter and then pulling it through to the take-up reel. Great idea...except at the end of the old reel, the motor simply rips the paper off the cardboard roll and pulls it through. If you do not catch the the filter at exactly the right moment, you will end up having to pull the entire unit out of the sump to replace the roll. This can be easily fixed by the manufacturer...just use stronger glue or use rivets to hold the roll in place. I hope they read this review to make that improvement.

Great product

Pros: Keep water looking great!!!!

Cons: Flees won't stick to roller when it's time to change rolls.

I really like the over all product. My water hasn't ever looked better since I have started using the clarisea. But they started using a cheap sticker to hold the flees to the cardboard roller, and it doesn't hold so you have to pull the entire unit out of the sump, and restring the unit. luckily it usually only goes through one roll a month.

The XL replacement has saved the day!

I was about to throw my sk3000 in the trash and go back to regular filter socks. The normal filter rolls that last "Months" were only lasting me 2 weeks and coming up very light in color.

These XL rolls saved it though. Its been on for 2 weeks and I've barely used any of it and the roll is coming up a nice dark color. Looks like they fixed the problem with the OG rolls.

They lose a star because the new rolls are more expensive and when they originally told us new rolls were coming they said they would be the same price.

Great improvement!

Pros: Lasts a long time, and removes so much waste.

Cons: none!!!

The new fleece rollers last MUCH longer, and filer out all kinds of junk out of the water. It almost shuts down my skimmer because of removing so much junk out of the water.
