Klir Drop-In Fleece Filter 101: Assembly and Installation

By far, one of the biggest husbandry complaints from reefers today is a filter sock. While the benefits of filter socks are undeniable, so are the frustrations. Filter socks help us keep our tanks clean by filtering water and trapping debris making it easy for us to remove.

The problem is that they still require us to remember to remove them. If we do not or forget to do so, the filter sock will clog up to the point that water will not get pass through them.

While this is not such a bad thing, the trapped food and debris within the sock will soon begin to decay and release unwanted nutrients back into the water.

Not only that, after removing filter socks, they are smelly and something we rather not deal with. Who hasn’t gotten the look from their signification other when you try to wash the filter socks on the same laundry machine that washes your families clothes.

Solution, fleece filter machine… or is it a solution really?   The fleece filter is a great concept… a machine that has a roll of fine clothe material. Water is ran through the material and filtered. As the material gets used and clogged up, the machine replaces it with new clean cloth. Once the roll is used up, the hobbyists tosses the dirty roll and replaces it with a new one. This sounds great but… yes, there is a but!!!

The current machines are expensive, they all require additional space within or above the sump and they all require intricate plumbing modifications, making it a hassle to install into existing setups.

The Klir filter by CoralVue is a machine that takes the best of both worlds to create a one-of-a-kind patent pending cleaning machine. Water passes through the Klir filter and as the filtering material becomes saturated with waste, the water level will begin to rise. 

When the water makes contact with the optical sensor, a motor is activated to advance new clean filtering material.

As clean material is exposed, water is now able to flow freely, lowering the water level in the sock tray and deactivating the motor. 

This process is repeated as needed, allowing you to forget about filter maintenance!

Unlike other filters on the market, the Klir does not take any additional space inside, above, behind or next to the sump. Simply remove your filter sock from it’s holder and drop the Klir filter in it’s place. The klir is a true plug-and-play filter!

Before we proceed with the installation, let’s make sure that our system is fully compatible with the Klir filter.

The sump should have:

  • A sock tray that is capable of holding at least 1.5” of water above the filter sock tray.If water does not collect above the filter sock tray, the Klir will not operate correctly. If you do not have a sock holder a special bracket can be purchased separately. Please visit CoralVue.com for all available accessories.
  • The sump should have no less than 8.2” of space below the filter sock tray
  • And, the sump should have a large enough opening above the filter sock tray to accommodate the footprint of the Klir.

In addition to sump compatibility, we also need to make sure that the Klir can handle the flow speed going into our sumps.

The number of Klir units needed is not based on the number of filter socks your sump holds. Just because your sump can hold 2 filter socks does not mean that you require two Klir filters.

The number of units needed is mainly based on total water flow going into the sump.

  • The Klir Di-4 unit can handle flows up to 750 GPH
  • The Klir Di-7 can handle flow up to 1800 GPH.

So if you have a sump that holds two filter socks but you are only moving 600gph, you technically only need one Klir filter. You can then install a diverter cap, which is sold separately, on the open filter sock holder to either close or reduce the flow that will bypass the Klir filter.

On the other hand, if you have the same sump and you are moving 1000 gph, you will need to run two Klir fiters in a master/slave setting where both Klir filter motors are connected to a single controller with a single sensor.

Now that we’ve covered the system requirements, let’s begin the Assembly & Installation of the Klir Filter.

Before we proceed with the assembly, let’s make sure that all components are included and nothing is missing from the box.

The Klir should include:

  • Klir filter body
  • One 50-micron filter roll

  • Controller

  • Optical Sensor

  • Power Supply

  • Motor

  • Fleece Supply and Collection Spindles

  • Rubber Vent Pipes

  • Additional collars just in case the filter sock tray in your sump is slightly smaller or bigger than the preinstalled collar.

To begin assembly, open the filter and insert the short-side of the rubber vent pipe into the holder leaving the long side upwards.

Insert the optical sensor into the slot on the main body and tighten the nut.

Assembly is now complete. Now it is time to thread the fleece in place.

Remove the cover from the unit as well as the sidewall from the bottom chamber.

Take the supply spindle, which is the larger of the two, and inserting it into the roll.

Load into the cradle making sure that it rolls over and not under.

Pull the fleece over the first guide roller and then under the second roller on the base of the unit.

Continue to thread the fleece down the bottom chamber and under and around the lower chamber guides.

Pull the fleece up the bottom chamber and then on the outside of the last two guide rollers.

Center and tape the fleece to the top of the collection spindle making sure the key is on the same side as the motor cradle.

Manually roll the fleece 3 to 5 full turns then attach the spindle to the motor.

Glide the motor into is cradle and then remove excess slack by manually turning the clean roll the opposite direction.

Put the cover back and place and finally, reinstall the bottom chamber sidewall.

Now, I’ll give you a private moment so you can say goodbye to your filter socks!!!

The Klir filter is a direct replacement for filter socks on sumps with sock trays. Simply remove your sock and insert the Klir. 

For tight installations, The Klir Filter hinges to a 90-degree angle, making it easy to install in tight spaces or under stands with low height clearance.

The final step is to install the controller. Attach the motor to the motor input on the controller and the sensor to the TS input.

Finally, attach the power supply to the controller and connect it to a power outlet.

Be sure to hang the controller in a dry area away from water. A drip-loop should be arranged for each chord connected to the controller. It will prevent water from traveling along the chord and coming into contact with the controller or electrical receptacle.

Your Klir filter is now ready to be used.
