Quick Overview

We have been waiting quite a while for a product like the Theiling Automatic Roller Mat. With the Theiling Roller mat it will automatically unroll fresh new fleece to trap and collect free floating debris and detritus from your aquarium. Usually anyone that runs filter socks in their sump will have a few handfuls of socks laying around that need to be cleaned and can take up quite a bit of space. With the 12v electric motor dirty fleece will be removed from the water allowing new media to take its place when the current fleece is starting to clog.

  • Automatic rejuvenation of mechanical filtration media

  • No more changing or washing filter socks

  • Detritus is removed from water column preventing the breakdown into ammonia

  • Drains can be plumbed directly to input or on a stand alone pump

  • 12v operation for low energy consumption

What are demensions of the unit?
Question by: Jim on Jun 30, 2016 6:28:00 PM
Dimensions are 17" long X 10" wide X 19" tall
Answer by: Connor (Admin) on Jul 1, 2016 9:29:00 AM
There is only on inlet I have two coming off my tank can for my drains. Can I merge to one or will I need to put another bulk head in the box?
Question by: Jared Voshall on Jan 6, 2017 9:15:00 PM
Great question! It is recommended to keep your drains separated where you can utilize one for an emergency and one for the Theiling Mat. Over the course of a 24hr period, your entire water column will have the chance to flow through the Theiling several times over. We have the same setup on the BRS 160! :-)

How high is the output from the bottom of the unit?
Question by: Shawn on Jan 7, 2017 2:34:00 PM
Great question! The drain bulkhead, which is the large one in the center of the unit, is 5.5" from the bottom. :-)
Answer by: Randy (Admin) on Jan 10, 2017 2:11:00 PM
How much clearance space is required above the unit's mounting location? It's 19" tall. How much space above that to remove the lid and replace the filter medium? Do you have to be able to get your arm in there to wrap it around the big chamber from the feed reel to the take-up reel?

If this is in a cabinet below the aquarium with a sump, space is at a premium, so I'm challenged to fit this in.

How does it mount? The plumbing is clearly coming out on one side, but it looks like the back isn't flat either, thanks to the motor sticking out. Seems like the motor should have been mounted on the front so you had at least one completely flat side to mount it.
Question by: David Bishop on Jun 20, 2016 3:06:00 PM
Great question!
In order to fully remove the lid with the roll you will need an additional 6" above the 19" of the unit itself. This does not really have a mounting option but rather can be placed in the sump on a stand or external on a stand.

Will my ato be affected as the mat fills up with detritus, and the water level rises to trigger the roller mechanism?
Question by: Ed E on Jan 26, 2017 8:53:00 PM
Hey there! The rise of water in the Roller Mat will affect your ATO, however the effect is very low because it takes several days for the water levels to change. The effects of dissipation will have a faster affect on your ATO versus the Theiling! :-)
Answer by: Randy (Admin) on Jan 29, 2017 7:53:00 PM
I wanted to know if this would work for my 720 or my 240 build? Thanks
Question by: Daniel Nadal on Jul 22, 2016 12:51:00 AM
Hi there,
The Roller Mat’s overall tank size rating will highly depend on the bio-load and overall amount of free-floating particles it needs to remove. For larger tanks, you may need multiple rollermats, as they are only rated to handle 600 GPH or you could have a stand-alone pump deliver water to the rollermat as well.
Answer by: Charlie (Admin) on Jul 22, 2016 7:43:00 AM
Generally how long do the felt cleaning material last before needing to be change?
Question by: Dan on Jun 23, 2016 10:44:00 AM
Great question!
Will vary on how much waste it put in however standard is around 2.5 months.
Answer by: Connor (Admin) on Jun 28, 2016 3:18:00 PM
How exactly can this be plummed ? Right now I have my 120 Gallon overflow that just uses gravity that falls into my 30G sump below into a filter sock. Can the roller mat just sit right in my sump, my water level on that side of sump is 9" high.? 10" wide seems very big!
Question by: B Roy on Jul 22, 2016 7:47:00 PM
Hi there,
The Theiling Rollermat can be plumbed in a variety of ways. The easiest would be to let your tanks main drain flow directly into the rollermats intake. It is not all that small, and if you could set it on top of your sump that would work, however the rollermat will need to freely drain into your sump. If you place the rollermat in your sump, you will need to be cautious of the water levels and how water how water flows through it. If you cut a rectangle out of cardboard or something stiff with the dimensions of 17 x 10 inches, then you could “test fit” it first.

Does it come with a mat fleece or do I need to buy that separately?
Question by: Emmanuel Becerra on Jul 9, 2016 2:01:00 AM
Hi Emmanuel,
The Theiling Roller Mat does come with 1x fleece roll. We would suggest picking up an extra just to have on hand for when it is time to change it out.
Answer by: Charlie (Admin) on Jul 11, 2016 11:59:00 AM
What warranty does it have?
Question by: Emmanuel Becerra on Jul 9, 2016 2:02:00 AM
Hi Emmanuel,
The Theiling Roller Mat comes with a 1 year warranty from the date of purchase.
If you have any other questions just let us know. : )
Answer by: Charlie (Admin) on Jul 11, 2016 12:00:00 PM

Full Details

Recommended flow rates between 200-600 gph through the Theiling Roller Mat.


Plumbing Info

Due to the manufacturer of this product being in Germany the bulkheads that are already installed on the Roller Mat are metric. If you wish to use US (standard) bulkheads for the input and emergency drain we suggest purchasing the Theiling Adapter Kit. Please note the main drain is a metric bulkhead that cannot be replaced with a standard bulkhead.


Main Drain:

40mm ABS Bulkhead - To convert to standard US size plumbing we recommend using the 40 mm to 1 1/4" adapter



40mm ABS Bulkhead  - To convert to standard US size plumbing we recommend using the 40 mm to 1 1/4" adapter


Emergency Drain:

25mm ABS Bulkhead - To convert to standard US size plumbing we recommend using the 25mm to 3/4" adapter


Dimensions: 17" long X 10" wide X 19" tall


Whats included:

1x Roller mat unit

1x Power Supply

1x Roll of Fleece

2x 40mm ABS Bulkhead

1x 25mm ABS Bulkhead


Your tanks drain line can be directly attached to the input of the Roller Mat, or a stand alone pump can be used. We do prefer to use a DC controlled pump for ultimate flow control but any pump up to 600 gph will do just fine.

  • great concept, needs fine tuning By nick on 2/10/2017

    This automatic roller mat is awesome in concept and reality, BUT the reality part needs potential problem solving to ensure long term proper function for some.
    As others have noted the motor and gears seem to be weak. Before mine have failed I noticed strange noises coming from the motor/gear. I believe its from the strain placed on both due to the excess moisture absorbed by the mat causing extra weight the motor has to move.
    This got me to thinking,
    A) is this because i have more moisture in mine than others? I'm not sure but i am plumed into the basement which has a consistent 65 deg temp.. Since this unit is enclosed i'd have to think 76 degree water enclosed and placed in a room 65 degrees will cause more moisture than if it was placed below the tank in the stand that more times than not is more toward 71/72 degrees, or more, causing less condensation which will lead to less absorption than my situation.
    B) If the noise i'm hearing is a result of extra weight absorbed by the mat, maybe drilling the top for better breathability reducing condensation would be the answer. I tried this by making 4 1.5inch holes. 2 directly above the feed mat and 2 above the dirty mat. The peaks of the cover- It didn't work in my situation.
    c) Remove the lid, everything else is wide open why not? So far this has worked i have no issue with full dirty or new rolls causing strain on the motor or gears. I also do not notice any smell from it being open (but it is in the basement and i'm not around it 24/7)

    Now that my roller mat is working properly i have no overflows out the overflow pipe and no weird gear/motor noises. Even with my tinkering it is still much less work than i had to do making sure filter socks are clean and not nitrate factories.

    I hope my findings help others in both decision making to purchase or problem solving down the road.

    Good luck, I still love it and it would easily be 5 stars if i didn't have to tinker!!!!!
  • Love this product By Fish girl on 2/10/2017

    I've had this for about 6 months. Love it, no problems. Reduces cleaning time.
  • See you later filter socks! By June on 2/5/2017

    We haven't been running filter socks on our 180 reef for years because of how often you need to clean them, but we do siphon out the sump a few times a year. We need to feed rather heavy due to the garden eel section of our reef, so when the time came to replace our 7+ inch DSB, we decided to add in the roller mat. Totally worth it! The brown gunk that comes out of the reef is nasty with a capital "N". We have a 45 breeder as our sump and while this is a tight fit, it works and I highly suggest it if you have the extra coin to go for it. We didn't need the adapter kit (bought and returned) but I'd suggest getting it just in case you DO need it since it would be a disappointment if you didn't get it and then needed it. Yes, it's expensive, and I know some people think its frivolous, but if you work long hours like we do and take a few weeks vacation every year, this is totally worth it not to worry about replacing/cleaning filter socks. And, this is coming from a lady reefer (1990's) who has cleaned many a filter sock in her laundry.

  • not perfect out the box BUT.. WOW By Swany on 12/14/2016

    ok first I had to make the inlet work with 1 1\2 bulkhead and switched the overflow to 1 inch ( the overflow can NOT be a 80 bulkhead its to thick and rubs on the roll) after that its perfection :<{)
  • Great product! By MP on 12/12/2016

    Less maintenance, less water change = fun hobby!!!
  • Great concept, still needs some work By Emmanuel Becerra, AcuaTV on 12/9/2016

    I have been using the rollermat on my system for 3 months now and I can say the following:

    - It is definitely the replacement of filter socks in an automated way.
    - Water quality is just way better since all of the detritus just gets removed physically before decomposing.
    - My pumps, reactors and in general all equipment is more clean, thus reducing the need to clean it more constantly.

    - You need a lot of space to fit this thing.
    - Even if you purchase the US bulkheads you will still need one to convert from Metric to English so that will require more space and in general will reduce flow on the rollermat.
    - The quality of the acrylic feels cheap and very fragile so handle with care.
    - At last but definitely not least the top cover has a major design flaw. Water condensates in the top part, causing water to drip slowly to the clear filter roll causing it to be soaking wet making it much more heavier and the tiny motor that the rollermat has is not strong enough to move it which causes the water to need to escape through the emergency overflow (thank God the designers did think about the need for it!). I'm going to have to drill some holes there to let water hopefully evaporate and avoid this problem, but this means that some of the smell from the old fleece will escape which is definitely a bummer. I plan to tackle this with some activated carbon in a foam bag or something like that to capture all the smell before it goes out.

    Things to consider
    - Some other reviewers complain that you need to use converters to make it work with US plumbing and rate this item low. I don't think that's fair since when you purchase it it clearly says that you need them so its not like you get an ugly surprise when you purchase it so please read the description well before buying so you know everything you need.

    I think the concept of this product is on the right track but it is nowhere near production ready, I would wait to see if they addressed these issues before considering buying this product.
  • Crystal clear By Michael on 12/1/2016

    After some difficulty with plumbing, yes I am an engineer, and gluing my fingers to the pipe. This thing works remarkably well. I agree with the previous assessment that the plastic is a little thin and I'm afraid it might be brittle. I purchased a different filter years ago made of what feels like the same material and have had tremendous headaches with parts breaking. The changing the fittings to standard isn't a big issue to me and works well. My full pump outflow is going through this filter of 981 gallons per hour and it is handling it wonderfully. If you look at the genius as to how this thing is designed it is simple which makes an elegant. I can't see how different flow rates will make a difference on the way the filter material works because it works by a simple head pressure difference between the outside of the roller and the inside, flowrate shouldn't matter. The gurgling sound it's outflow makes I can't reason out a way to change that or make it stop, but it sounds kind a like ocean waves so that's cool. The cost is still very high for what it looks like after you get it out of the box but any new product with limited distribution is going to cost a lot. I did do the three prerequisite visits to the hardware store. I would highly recommend diagramming out your plumbing and even coming up with a bill of materials, this thing is not easy to plum. I have it raised to where the outflow it's just above the top of my sump I didn't want to cut any holes in my brand-new Ruby sump. My first attempt leaked in two places, in a coupling I had to use in my existing piping in order to change the piping after the ball valve to get it to go to the inflow and the other leak was I put the bulkheads on backwards so I could just press the inflow and the emergency drain in, a lot like the outflow in order to be able to easily remove the unit for cleaning. The second visit was getting new pipe after the coupling and changing the bulkheads around and using nuts instead of press fitting. The third visit was dummy me on the ball valves I forgot to put the tightening ring on before I glued it, was not pretty. The ball valve is the expensive one from BRS and the ones at the hardware store were too cheap. I didn't have enough pipe left to use another coupling so I ended up cutting it right at the ball valve fitting. I was going to drill it out but stupid me bought a 1 inch drill and that is the inside diameter, so it didn't do anythind. What I did do and this was a little bit a genius on my part was sanded the two ends where I had to make the cut to put the tightening ring on and then used gel superglue and man does that stuff stick, that's where I glued my fingers to the pipe.
  • So far so Good. By David D. on 11/30/2016

    I have been running this bad boy for about 2 months. I had to change my design for my new sump several times to utilize it. The way that the sides are a little sloped and the size of the filter, not to mention the pipe outlet placement, make it a designers nightmare. It is made for ponds more than aquariums, BUT, that being said. It is awsome. I have a new tank with all my old live rock and new sand etc. In two months the used roll is pulling off a lot of silt and my first good algae breakout. I thought this thing was going to use up rolls quickly and I was wrong. I am still on my first one with my return pump pushing well into the 600's. I have found the outflow to be a litte noisy with the gurgle noise but I am coming up with a plan to help with that. The lid is a little cumbersome and could have had deeper ridges to make it fit more easy. The plastic could be a little thicker. I feel like I am going to crack it all the time. I had a cracked return gear after I first started using it (manufacturing bubble in the plastic), but the guys at BRS helped me get a new one. I look forward to them carrying replacement parts for it so it doesn't have to ship from Germany. For the first time in 6 years of aquariums, I have not had to jack with filter socks every three days. I am very happy with how it is turning out.
  • Awesome filter- need a US version By reefmonkey on 11/29/2016

    Awesome filter like the above reviews- the only sucky thing is that after spending this kind of money you need to either purchase adaptors for US fittings or modify the filter to accept US fittings. Either way seems a little silly when you are purchasing something that beats the standard (sock holder and socks) due to pure convenience.
  • I have an Observation! By ClownMan on 11/21/2016

    My observation of the design of the product is that as the fleece material is being wound up on the discard roll the detritus and partials are being squeezed back into the water?
  • Roller Mat Bliss By Idol on 11/3/2016

    These units are worth ever penny. No more filter sock blues. I have 2 units in a 40 breeder to run my 240 gallon reef and it makes my life simple.
