- Di-4 Drop-In Fleece Filter System - Klir
Months of Maintenance-Free Filtration!
Klir Di-4 Filter Drop-In Fleece Filter System fits in most sumps with a 4" 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-4 has the capability of handling up to 750 GPH and producing crystal clear water.
Maximum Flow Rate - 750 GPH
- Fits in tight areas
- Compatible with most 4" filter sock holes
- Includes 25 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-4 Drop-In Fleece Filter System, you can throw away your filter socks for good! The Klir Di-4 can hold up to 25 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-4 Works
Water will be able to enter the Klir Di-4 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 don’t have to use dremmel for a $250 item to work By Samir on 1/20/2019Samir wouldn't recommend this product to a friendI feel they jammed this product out trying to compete with ClariSea. ClariSea is in a whole different universe. This product is a disappoinment. I wish I would have read the posts on it on reef2reef before buying. From water sensor and controller not working to fleece getting ripped by super sharp 90 degree turns, this is one huge disappointment. I had to use dremmel extent]sively to smooth out the edges where the fleece makes sharp turns. I don’t recall a last time where I had to do so on a piece of equipment that costs $250.
Go with the Rollermat if you can By Greg on 1/11/2019Greg wouldn't recommend this product to a friendBesides not fitting in my skimz sump (which I modified and eventually got to work) the information and communication has been horrid from Klir as to what sumps this can fit in. What they don't tell you is the water level sensor sticks out the side and adds further to the dimensions of the unit. If it gets any larger particles in it such as a grain of sand it will jam the rollers and not let the fleece turn which leads to the motor pulling so hard it rips the fleece then you have to take the whole thing apart and re-route the fleece which takes forever compared to the advertised 45 seconds on the compact rollermat. Water also sneaks by and not 100% goes through it unlike the large rollermat (havent used the compact yet). I know this because I am still cleaning out a filter sock that comes after the Klir once a week! Roll of fleece lasted me a month which I guess is okay. The motor is defintiely the strong point as I mentioned it's so strong it will tear the fleece before it stops moving. Its a good concept but stay away from this
Works well after modifying Red Sea sump By jesse on 12/24/2018jesse would recommend this product to a friendModifying the sump was not an easy task. I siliconed fiberglass to allow the water level to rise > 1.5" for the sensor to work properly. The hardest part was shaving the Klir plastic insert down so that it would fit properly into the sump filter hole. Since I have an apex, I used a float switch to shut off the Klir Filter when the sump water is high. That way the Klir Filter motor doesn't just consistently run whenever the sump water level is high during feeding, return pump failure, etc...
After the modifications were made everything else with the Klir filter has been working great. I've been running it for over a month. I was expecting poor results due to all the negative reviews, but I have been very happy so far!
Works well, not sure about longevity By Andy on 12/7/2018Andy would recommend this product to a friendPicked up a Klir and extra floss rolls during the Black Friday sale. Nice design, well packaged. First issue occurred after a week, Klir started to consume tons of clean fleece. Contacted CoralVue and they told me the sensor may be dirty and they would send me a new controller with updated logic to prevent this issue. Great customer service, but the controller seems very cheap to me, I just don’t think it will last near a harsh saltwater environment. Hope I’m wrong.
Wouldn’t buy again, pain to use By Jo White on 12/5/2018Jo White wouldn't recommend this product to a friendI was super excited to finally be able to preorder and receive the Klir Filter after seeing it at RAP only to be disappointed by it not being user friendly. It’s a pain to load a new roll into the unit as it is enclosed, the roll unravels and catches in the hinge when you close it. I’ve already had to have a major component replaced as it malfunctioned wasting an inch thickness worth of fleece. It also gets caught on itself when rolling at the beginning of a new roll and at the end of its life which causes it to tear. This leads to water pour through and not being clean. I only figure this out once the skimmer goes crazy from the water not being cleaned. The inside rollers also accumulate goop from the dirty sheet rolling along them. It’s gross, like skimmate. For all the money and hype I’m beyond disappointed. I would not buy this again and don’t recommend it. Worst part being I modified my sump and drilled out my filter sock hole so changing methods is going to be a nightmare.
Waste of Money By Mike on 10/31/2018Mike wouldn't recommend this product to a friendI have been running this filter for two months now and the filtering has been extremely disappointing. Your led to believe it will filter your water and keep your water looking good with the 50 micron filter media but it does not. I have already had my skimmer pump shutdown twice clogged with debris that passes through this filter. Sure it claims less maintenance but it is simply not worth having a dirty system. This has been one of the worst purchases I have made for my aquarium, truly disappointing.. I do not recommend to anyone. Use at your own risk.
Great Idea Disappointing Product By SaltMan on 10/26/2018SaltMan wouldn't recommend this product to a friendI was really excited to see this product come to life and eliminate the need for filter socks but the product just does not perform very well. I have had it installed since the release date and while the used roll is dirty my sump is incredibly dirty in just two weeks. With a 50 micron filter I would expect my water to be fairly clean but I can see more particulates floating around and with the debris that is in my sump it is really disappointing. 2 stars rating and I would not buy again as it's design is right now.
Happy wife, happy life! By Roberto on 10/22/2018Roberto would recommend this product to a friendBeen working just as intended for a few weeks. Truly a “set and forget it” device. I would have already had to use the washing machine multiple times to clean my old socks. Needless to say my wife is very happy!
Very happy user By Carissa on 10/19/2018Carissa would recommend this product to a friendI read other reviews but in my personal experience, the Klir works great. I installed it and it works as it should. I am thrilled that I don't have to deal with my old filter socks anymore.
Small issue but working great now By Kyle on 10/15/2018Kyle would recommend this product to a friendI had a small issue with my unit using up the entire roller in one night. I woke up one morning only to find out that the motor had used up the entire fleece overnight. Sensor was clean. I contacted support and they sent me a new fleece and a new controller. Have not had the issue since. Very happy with it now!
Popping and cracking when motor turns By Matt on 10/13/2018Matt would recommend this product to a friendA couple days after installation it started making loud noises that sounded like gears stripping. Loud popping and cracking. After taking motor and dirty fleece reel off I tried holding the motor shaft with one hand and activated the motor. No matter how hard I tried I couldn’t stop the motor shaft from turning. Obviously no stripped gears and this thing has an enormous amount of torque!!! So then I put the dirty fleece roller on and could easily spin it and it was popping and cracking. The clear plastic end cap on the take up real was spinning inside the gray tube. I removed the end cap completely out of the tube put several drops of super glue just inside the gray tube and slid the clear cap back into the tube. Let it set for a couple hours and reinstalled everything. It’s been working perfectly since then and is amazing. Completely silent.
Just a minor inconvenience but now works perfectly By Aaron on 10/11/2018Aaron would recommend this product to a friendIt was originally disappointing when I experienced the issues of the motor not being able to turn the roller and of wasted fleece like others have mentioned. Turns out that the dirty roller was faulty and spinning in place. I contacted support and within a few days I received a new dirty roller spindle. It's been working flawlessly now for two weeks without any intervention. my Water has never looked clearer
Starting at: $9.89
Will this work with a Red Sea Reefer 250 sump?
Great question! This will work with the reefer 250 assuming you do not have the glass ATO box on top of where the filter sock usually goes. There will also need to be a modification done as the Klir needs about 1.5" for the water level to rise above where the filter sock trays usually go to trigger the sensor. The reefer has 9.5" clearance and this needs 8.125" to drop down into the water. The rest of the unit will be above the water line.
Hope this helps, have a great day!
Any reviews on this? Also, any idea if this will fit into a trigger 39 sump filer sock area?
We currently do not have any reviews for this Klir, but it has just released, and I would expect to see some soon. Using this with the Trigger 39 sump is possible, however you would have to modify the cover portion to make this work, as the Klir extends too high out of the sump.
