- 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.

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
Good idea but they should've done more tests By Thomas on 2/27/2019Thomas wouldn't recommend this product to a friendThe fleece jams when it gets dirty , also the motor does not seem strong enough to roll up the fleece, I find myself manually rolling up the fleece to help out the motor. Also the plastic spindle/ holder that comes with the unit fits perfectly in the metal housing that goes to the motor but the ones that come with the replacement fleece does not fit and I have to re-use the old one. Hope they are able to build a stronger motor and get new plastic spindles / fleece holders that fit.
Correction, product with design flaws By Melvin on 2/24/2019Melvin wouldn't recommend this product to a friendFirst perception was great product till some problems arose. As several other reefers stated. There is a need for a rounded edge or roller that was missed in the design. The other cure that would help is a motor with more torque. The Di-7 uses the same motor as the Di-4. That makes no sense trying to pull almost twice the mat with the same power motor. Get smart with refinements Coral Vue. You should correct the problems at no charge to all the reefers that bought these Klir fleece roller systems.
Great Concept, Poor Design By Colin on 2/14/2019Colin would recommend this product to a friendSo I have been waiting for the Klir before the Klir even looked like the Klir does now back when it was an odd design with legs and expansion trays. Anyway, I recently upgraded to a 300 gallon reef and have a 120 gallon MRC sump with three 7" sock holes. In an effort to keep the other two sock holes open I 3D printed 7" round tubes that are 3.25" tall in case the Klir fails and forces water to go above the sensor it will prevent a flood.
Now to the Klir itself. After opening and watching the not so amazing setup video (why they don't have instructions is beyond me) I placed it in the sump and waited for it to start collecting waste. Unfortunately, for the first 3 days I found the motor struggling to pull the fleeces from the clean side to the dirty as there was too much resistance. I contacted CoralVue (Carlos answered) who had me check a few things and was only really able to tell me to look for a snail or something jamming the roller (impossibe as the tank has no inverts yet as it's 1 month old). After explaining the problem spot being the sharp turn right after the second roller I told him I would try sanding it with a dremel to round it out. Carlos explained I could try it, but they have been running the unit for over a year with no problem of this type (I also find this to be nearly impossible given the reviews). But finally after fighting with the Klir for days on end wasting nearly an entire roll of fleece I have the filter working flawlessly and am happy with it. Although I don't believe out of the box modifications on a $300 filter sock is acceptable, I am very happy to have it working as intended and not in the garbage.
So overall I would say if you have a sump like mine with filter sock holes and want an easy to install solution I would purchase this again but do not be fooled into thinking you'll just throw it in and be good. Make sure to save the headache and use some 220 gritt or finer sand paper to roll out the sharp corner after the second roller (clean side) and reduce the drag so the motor can easily pull the dirty roll up! Sorry for such a long winded review. Hope it help! Happy Reefing.
Great product "update" By Melvin on 2/12/2019Melvin would recommend this product to a friendThe Di-7 is a very good design. A clearer instruction sheet with a side view of installing the Mat through the rollers on paper would be great help. "just like under the hood of a car for a serpentine belt" You have to pay attention to threading the mat. If you do it wrong it will bind. The only thing I dislike is the low tide smell from the roller mat. I had a problem with the controller not functioning correctly. I made a call to Carlos and they shipped my out a new part. This to me is still a lot easier to load the mat into than the Theiling Automatic Rollermat. The Di-7 replaced the 2 Theiling Automatic Rollermats.
Great idea bad design By James on 2/9/2019James wouldn't recommend this product to a friendI have now spent several hours on different occasions trying to get this to work. The fleece binds up in the system and the motor is to weak to turn through system. Great idea wish it worked guess I’m out 300 and going back to filter socks. Brs should really test all new products I am sure I will not be the only one to have this same problem
