- 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.

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
Customer support was fast and now it works great! By Heather on 10/10/2018Heather would recommend this product to a friendThe unit works great for me. I had an issue with the machine making a cracking and screeching sound as one review mentioned so I contacted CoralVue and they determined that the issue was the waste roller. They sent me a new roller which I installed and the issue was resolved. No more screeching or cracking sound and the unit has been working great so far!
Does not work By Marion on 10/4/2018Marion wouldn't recommend this product to a friendPut this in my sump and it did not work. my husband tried to modify it, still didn't work. What I find ridiculous is the device has to be put in water to find out if it works, once it is in water Bulk Reef Supply won't accept it as a return, so I can't return it and I'm out $250.00. Irritating!
Good idea but needs improvements By Matt on 9/30/2018Matt wouldn't recommend this product to a friendI bought 2 of these for my 6' tank due to high flow through the sump. They don't have the controller to link them both so I had to try and adjust the sensor height to keep them balanced. After the first week one roll was half spent and the other barely turned. By the second week one of motors couldn't pull the felt through and would just make a screeching sound and seized. That fleece was less than half spend. As much as I like the idea of these, I can't afford to be dumping $30 every couple of weeks into new felt rolls that are mostly clean. I will be sending them back. Guess its back to filter socks until they make a better/stronger design and have the controllers to make them work together.
Great Idea, Poorly executed with no customer support By George on 9/26/2018George wouldn't recommend this product to a friendI have been trying to make this system work for almost three weeks now. As a chronic "early adopter" I am used to working through problems with "new to market" products. This product is a SUPER idea. I was so excited to see it that I bought is as soon as I saw it advertised. I set it up as soon as I got it (even though there weren't yet any instructions - even online). While a great idea, it just doesn't work. My filter floss has broken many times and I'm now tired of restarting it, so it's back to the old sock regimen for me. I have tried getting help from the Coralvue support system, and Carlos has told me that even though it's rated for 750 gmp, my 750 gpm system is just too much for it to handle...then when I pointed out to him that my problem was filter floss breakage, he told me that I must be getting snails or particulate debris in the system to cause it to break. I can tell you that there haven't been unusual snails or debris visible in the filter path. I'll probably play with mine to try to get it to work (I think there is a manufacturing/design problem that I can fix and probably get it working for me), but for 250 bucks it ought to work right out of the box, IMHO.
Does not work with Red Sea Reefer sumps (yet?) By Mike on 9/23/2018Mike wouldn't recommend this product to a friendI bought this and was excited to get it all setup. Unfortunately, the Red Sea reefer sumps do not have enough water volume above the sock area to trigger the optical sensor that makes this unit work. From comments on Coral Vue's site, they will be selling an adapter but as of right now the only way to make it work is to engineer your own extension.
Starting at: $10.99
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.
