- Di-7 Drop-In Fleece Filter System - Klir
Months of Maintenance-Free Filtration!
Klir Di-7 Filter Drop-In Fleece Filter System fits in most sumps with a 7" filter sock tray and will eliminate the need to replace filter socks. The 50-micron fleece roll will help eliminate free-floating particles and automatically advance when the fleece starts to clog, exposing new fleece. The Di-7 has the capability of handling up to 1800 GPH and producing crystal clear water.
Maximum Flow Rate - 1800 GPH
- Fits in tight areas
- Compatible with most 7" filter sock holes
- Includes 50 yards of 50-micron fleece
- Fully automatic with smart controller
- Removable lid with carbon insert for noise and odor control
- Multiple units can be placed side-by-side
Traditionally filter socks have been used to polish aquarium water from particulates and detritus, and now with the Klir Di-7 Drop-In Fleece Filter System, you can throw away your filter socks for good! The Klir Di-7 can hold up to 50 yards of 50-micron fleece allowing it to last for months at a time without having to be maintained in any way. The compact design lets it fit in tight spaces, and since you only need to access it once every few weeks or months, having direct access like filter socks in no longer a concern. Some tanks may need to replace the fleece once every couple months where others may need to replace it more often, and that will depend on your bio-load along with feeding habits and a few other variables, but in most cases, a single fleece roll can last up to 3 months without having to be replaced.
How the DI-7 Works
Water will be able to enter the Klir Di-7 from two sides and then travel down to the bottom where it can be pushed through the fleece material, where any particles will be collected. Over time the debris collected will start to clog the fleece tower and the water level will start to rise in the sock tray, and that is where the optical eye sensor comes into play. Once the water level reaches the eye, the Klir will automatically activate the roller, exposing new fleece and allowing water to flow freely again, dropping the water level below the sensor.

No longer sucks! By Reefer93 on 2/24/2020Reefer93 would recommend this product to a friendOkay so the original version was absolutely garbage. It would always bind up and was unreliable. After talking with Coralvue I got the new upgraded motor which is faster and more powerful. I can now leave town without worrying about it and it works as it is supposed to. With anything electronic there is always room for improvement but I can say without a doubt I’d buy another one...
New 11 RPM motors actually work! By FL Coral Grower on 2/11/2020FL Coral Grower would recommend this product to a friendAlright, so the first version of this filter was horrible. I bought six for a commercial facility and ALL of them did not work, the fleece would tear with the slightest bit of friction when the motor would turn. I was considering throwing them off the roof just for a relief of stress. HOWEVER...after discussions with CoralVue, they sent all new motors and fleece rolls which are working GREAT and the filters now work as they are supposed to. The new motor is much stronger, the RPM shown on the motor increased from 3 on the old one to 11 on the new ones. It is a relief to know that they at least listened to feedback and made a change to the design, and the unit now works well. I would recommend giving these a shot now that the new motors are available, and check that your motor is 11 RPM rather than 3.
Save your money, it doesn’t work. By Haz on 7/15/2019Haz wouldn't recommend this product to a friendTrust me. I tired everything possible to make this work but it doesn’t. These items should be recalled. I am being generous by rating it at 1 star.
Units are defective and should be recalled! By Haz on 7/2/2019Haz would recommend this product to a friendIt’s just doesn’t work. They sent a new sensors and then new controller and now I have been waiting for a new motors for 2 months. are they said the motor isn’t strong enough to roll the fleece.
Re-reviewing my original post By Reefer93 on 5/31/2019Reefer93 wouldn't recommend this product to a friendAfter now running this for 3 months I would no longer recommend it. I originally gave it 4 stars after having to modify it to make it work but now it's a frequent pain in my A$$. I cannot get through an entire roll without some problem which is usually the fleece binding on the dirty roll against the side of the unit because the spindle is not level in the cradle. The only way I can describe the motor would be the engine of a Toyota Prius placed in a Chevy 3500hd. The motor is miserably weak for the job, and a simple rub at any point in the assembly puts you dead in the water. I could go on and on about all the imperfections but I think you'll be better off saving your time on reading and rigging this $300 filter to work and look at a different product. Happy reefing.
I got it working after a few lessons learned and wasted rolls of fleece. By Justin on 5/22/2019Justin would recommend this product to a friendSetup: I'm filtering a 160G display tank with a 90G sump. According to my Neptune flow meter, i'm seding about 470GPH through my return plumbing.
1 - Wet fleece / motor not advancing
2 - Beeping / wasted fleece
1 - Wet fleece. It's important to not get the fleece wet when installing the filter. The water in the clean filter spool causes bacteria to grow in the clean fleece and the weight of the water makes it significantly harder for the motor to turn the spindle. I ended up removing the acrylic top cover, which only function is to 'contain' the dirty fleece behind a thin carbon filter in the top of the unit that is supposed to address odors. My experience is that, with the cover/carbon filter off, the clean fleece stays dry and the dirty fleece dries out, and oder hasn't been a problem for me.
2 - Beeping / wasted fleece. If the motor advances the fleece by a certain amount and the sensor is still detecting water, instead of spooling the entire fleece roll from clean to used, the unit will stop spooling and start beeping. There were several times I was woken up by my annoyed wife compaining of beeping from the reef at 2am. Not super fun. With 470GPH and how my sump is layed out with an adjoining refugium, the water level was JUST below the sensor. A little froth would cause the sensor to trigger, which meant I was consuming fleece much faster than needed. The first thing I did to address this was to position the filter so that the three 'open' sides of the filter faced the water flow, and the blocked 'hinge' side faces the front of the sump which is in the 'shadow' of the majority of flow through the sump. This sent more flow through the fleece and lowered my water level a bit. The second thing I did was 3D print a PETG 'riser' that raises the base of the Klir about 1/5" higher above the filter sock tray. With those two modifications the sensor only triggers when the fleece is truly clogged, and I'm using much less fleece and the fleece is much 'browner' on the use fleece spool. Most users shouldn't have to print the riser, I think this was somewhat due to my sump layout and the adjoining refugium which kept the water levels higher in the filter sock compartment.
Recommendations to the manufacturer for version 2:
1 - ditch the acrylic cover / carbon air filter. Save the cost of those parts and spend on a slightly more torqy motor or more adapters so folks can dial in the height of their filter
2 - Maybe make the top secion 1/2" taller, and allow for more adjustment in the sensor placement up and down.
3 - Allow for the beeping alart to be turned on/off on the controller. I'd prefer to just let my sock tray overflow than to be woken up by beeping. Others may want the beeping.
4 - You already supply 3 different sock try adapter sizes, maybe include two of each and a longer plastic screw, or include an option spacer layer or two so users who need to can raise the top up 1/4" or 1/2" up of the filter sock tray.
Overall I LOVE not dealing with filter socks, but this wasn't quite as plug and play as I expected. Now that I have it dialed in I hope to never go back to traditional filter socks!
Not worth the money. By Michael on 4/9/2019Michael wouldn't recommend this product to a friendFor 300 bucks, I should have been able to in stall this filter and have it run properly. That wasn't the case. Right out of the box you could tell there were going to issues with the felt feeding correctly. Too many sharp edges and rollers to deal with. The felt would not advance, it would clog and send the water out the overflow of the sump. I tried to contact the manufacturer, but they didn't answer my email, they don't have phone support. I contacted BRS, and they sent an email to them. Carlos answered the next day. After a few emails and many pictures and videos sent to Carlos, he sent a new sensor and controller to me, and I switched them out and no surprise it did nothing to help it work.
So i looked on line, and tried everything other people have done to fix their filters. Round the edges where the felt drags across the plastic helped. but it would not work for long. I by passed the rollers that make the felt turn 90 degrees around the now rounded corners. This seems to have helped. The filter has been running for 2 days now the way it should. I wouldn't recommend this filter to anyone but the few who are looking to modify it from the start.
disappointed By RT on 4/3/2019RT wouldn't recommend this product to a friendToo man sharp turns for the fleece sheet to travel through. One corner in particular seems to the the issue. Poorly designed. Motor is weak. This thing jams every day. I have had to roll it through manually. Instruction video is great for the 4 inch model but there seems to be an additional roller on the bottom of this thing that doesn't exist on the 4". What an amazing concept but has been a huge failure for me. Corlavue should strongly consider a recall.
Initial release has some issues, tech support fixed it. By Jeremy on 3/30/2019Jeremy would recommend this product to a friendI bought this soon after it came out (about 5 months after the 4" one came out). After solving one problem (below), it works great. I have it on my Eshopps R-200 sump, and I like it.
The one problem I had, was almost like what others have found, that the fleece didn't roll up. In my case one of the bottom rollers would lock in place. CoralVue's tech support got back to me the same day, and we tried a couple things which didn't work. Eventually they sent me a replacement for the whole bottom piece.
I do believe the motor could be a little stronger, and they recommended to me to Dremel the first corner (as others here have described), and that doing that would NOT void my warranty. I have not smoothed that corner on the new piece, and am having no problems.
One more thing I'd recommend: I noticed that a small amount of water goes under the plate that should sit flush with my sump. (I'd noticed it with my filter socks, too. So not a new problem.) I'm going to buy a small mat (https://www.bulkreefsupply.com/foam-tank-mat-mr-aqua.html) to act as a gasket between them.
Great Concept, Poor Design By Mitch on 3/20/2019Mitch wouldn't recommend this product to a friendFailed right out of the box.... made several attempts to correct the issues with Coralvue Tech support all failed.. don't waste your money
Poor Design By John O’Keefe on 3/11/2019John O’Keefe wouldn't recommend this product to a friendI bought the Klir 7 “ model with high hopes for a solution for filter socks and the fact that BRS would choose to carry it. Well.... my hopes were crushed when right out of the box my controller and water sensor were defective. After what seemed like too many emails with photos of the unit not working, remember brand new unit, I received the replacement parts. Now the fun begins, the motor that turns the fleece is very weak. The clean roll sits in the housing and once it is saturated with water gets heavy and hard to pull. Several times the motor has alerted me that it was stuck because the roll was too heavy to pull. Once I manually advanced some clean paper the motor could pull up the used fleece. Because of spending the $300 and not being able to return it I had to figure ways to make this thing work. After multiple ideas and attempts I have settled on unrolling the clean paper and folding it over into a pile about 8 inches square and places them between the sump and my cabinet. Also this thing seems to really let a lot of flake food and other debris into the sump which I vacuum weekly. I bought this unit because I am tight on space and the drop in aspect seemed attractive. If I had known about the problems I was going to have I would have stuck with the filter socks, what a shame......
Beeps everyday By Adam on 3/4/2019Adam wouldn't recommend this product to a friend1 week in and I haven’t gotten it to work for 24 hours.
First the fleece needs to be installed perfectly straight so it doesn’t clog.
2nd I had to use gaffe tape to get the fleece to hold on the roller and create a tight roll other wise it would jam
3rd the sensor. Well the sensor has very little adjustment so with the R-300 sump the sensor was too high causing the water to spill over the overflow instead of hitting the sensor causing froth to build up and foam over the sump. The foam also caused the sensor to spin the motor non stop and constantly beep.
I’ve adjusted the sensor best I can but still haven’t gone through a 24 hour period where the sensor causes the motor to spin too much and beeping. I just need to wipe off the sensor from a splash and it stops beeping but it does waste a lot of fleece when this happens.
Over all this is an annoying product with a lot of potential. An adjustable arm for the sensor and maybe an option to add a float switch or a better quality sensor, and a fleece roll that has a better way of attaching to the roller would make this product better
