- 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 gary on 3/31/2020gary wouldn't recommend this product to a friendThis thing would probably be great if it worked properly but it doesn't. Too much water pass through without being filtered. My roll never advances, waste of $250
Finally a working product!!! By Andrew on 1/8/2020Andrew would recommend this product to a friendI have been eyeing these up FOREVER! I hate filter socks, have a nutrient problem, and have a VERY limited space for additional equipment. The DI-4 is by far the most compact rollermat on the market, but the reviews have been TERRIBLE!
After reaching out to coralvue they confirmed all units have an upgraded motor and a slightly modified body to resolve the countless issues plaguing them in the past. I refuse to have the unit cause more havoc to my system, so i put the known failures to the test right away.
These are known for binding up when trying to advance the roll, and gets even worse when the role is wet, so what did i do? Dunked the entire brand new roll into my tank, assembled the unit, and tried to advance the role... IT WORKED!!! The new motor and design have done a wonderful job thus far. I would recommend NOT oversizing the unit though. If you need a DI-4 don't buy a DI-7. The filter paper on my tank advances about .5in/day, meaning detritus is left in the tank for about a week before fully removing from my tank. In an effort to help this i have increased flow, and even now and again "flood" my sump to force the roll to advance a few inches.
All in all I'm only 3 weeks in, but would 100% recommend the product to others!
*designers suggestion* the fresh roll slips out of the machine too easy when trying to mount into your sump. A tighter fit or a locking clip would be convenient
Absolutely love my Klir4 By David on 10/9/2019David would recommend this product to a friendAt first I was skeptical because it didn’t fit perfectly in my Waterbox 100. it fits over the hole and seals it perfectly for my needs. I’ve had it for almost 2 months before I had to change the filter. It works really well, I’m so happy I got rid of filter socks. The only con is that it doesn’t fit perfectly in the hole but it fits over it. I still get a good seal. And the same goes for the diverter cap. It doesn’t fit in the hole, it fits over it.
Save your money! By Haz on 7/2/2019Haz wouldn't recommend this product to a friendI have purchased both. The klir Di4 and Di7, the issues with it are endless. From issues with the sensors to issues with the motor. So far I have replaced the sensor, I have replaced the controller and now I have been waiting for a new motor for two months and still nothing arrived. I was told at the end after replacing everything that the motor is actually not strong enough to pull the fleece so until then I have both units collecting dust. The worst $1K I have spent in this hobby.
Design flaws By Chad on 5/14/2019Chad wouldn't recommend this product to a friendIt is easy for water to pass around the edges of the fleece rather than being forced through it.
DO NOT BUY! By Haz on 5/9/2019Haz wouldn't recommend this product to a friendIf you want to try you luck go ahead and get.
I have both the 4” and 7” and they both do not work and unreliable.
Roller always stuck, dirt passes through easily, controller break often, sensor breaks often, lost few rolls because it was stuck, the motor struggles to pull, the paper was cut in half but while being pulled by the motor because it doesn’t have smooth edges, the list goes on.
Both devices are out of my sump.
Worst decision ever made was to get this filter.
Works very well By GEORGE on 3/21/2019GEORGE would recommend this product to a friendAfter modifying my red sea reefer 350 filter sock area to work with this unit, it is great. I have not changed or WASHED a filter sock for 21 days. The filter roll appears to be only half used up so far. What a work saver. Either the new ones are better or people do not have the proper install setup. Normally I changed socks every other day because they were over flowing, now that is one less thing to do :) . I have to say that the water is very clear, but not crystal clear. Only in very bright lights can you see the extremely tiny particles the filter lets by. Not 50 micron, so it must get by the sides of the filter just a little. I'm picky, but no way I would go back to filter socks again. It took a little silicone caulk and acrylic sheet to modify my sump, but it was worth it.
Love this thing By Matt on 3/5/2019Matt would recommend this product to a friendI have been running the Di-4 for about a month now, I am still on my first roll, and I have had zero problems. I have a Waterbox 70.2 and put this in the first filter sock holder. I absolutely hate cleaning filter socks and this product was the only drop in option for me that worked without changing anything else. One of the best parts is that it is constantly removing the crap it collects from the water, unlike a filter sock, which holds all off it in the water until you manually clean it. Water in my DT and sump seems to stay cleaner and the enclosed design w/carbon keeps me from smelling anything. I have nothing but good things to say so far and I highly recommend the Klir.
just don’t work right By firechief on 2/17/2019firechief wouldn't recommend this product to a friendThis thing just doesn’t move the paper. Alarms go off multiple times day and night. roll the paper a little and works for a short time. Not for $250.00 bad move on my part.
Read Reviews, Thought I Could Do Better, Don't Buy. By Travis on 2/17/2019Travis wouldn't recommend this product to a friendI read the reviews about the hit & miss performance.Some happy, some pissed. I thought maybe if I just invest the extra $100 into Klir's own filter sock bracket that is designed to give the PERFECT conditions for it operate the thing will work optimally. So now I have $350 worth of equipment that is supposed to replace a $5 filter sock & make my life easier.....
(Replumbed my tank for it, rearranged my sump for it, changed my water level to accommodate its needs.)
#1 They included a broken part with my order. (No big deal things happen, they send me a new one a week later)
#2 They send me a broken controller that cycles through an entire roll of $12 fleece in an hour (Now up to $362)
(No big deal things happen, they send me a new one a week later)
But at the end of the day it lets all kinds of gunk through, the seal is far from perfect on the fleece so its even a bad version of probably the most basic piece of equipment in our hobby. The fleece CONSTANTLY gets stuck on gunk at the bottom of the rollers meaning a 10 minute project to pull it out of the sump and redo everything.
So now my choice A. Take this thing apart every 3 days to manually roll the fleece forward on my $350 filter sock
or B. Chuck it in the trash
I have been on the phone & email with CoralVue/Klir customer support.
I am not confident in their ability to resolve this - at this point with the level of experience I have with the project I view it as a half baked prototype rushed to market & I'll just waste hours of my life when at the end of the day it's just a bad design built to only operate in a sterile tank full of fresh water.
DON'T MAKE THE INVESTMENT -Even if they send you all the right parts and unlike most people it DOES work and not jam.....It still doesn't filter 50% of the stuff & it will end up with you cleaning that gunk out of your sump. It seems like a joke even as I type this. I don't even leave bad reviews (or any reviews for that matter) But I was just so fed up with this product that I wanted to warn others about how truly bad it is.
Inconsistant Results By JDG on 1/28/2019JDG wouldn't recommend this product to a friendThe advance roller fails to take up dirty fleace due to binding in the bottom turn around portion of the filter.
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.
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.
Does this fit in the skimz sumps?
Will this fit in the Trigger Systems Sapphire 20C Sump?
I am afraid it will not, the opening for the filter sock is too small.
