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
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.

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.

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.

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. : )

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.

  • 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.
  • Awesome... great concept and worth tinkering with for max performance By Rupert on 9/21/2016

    I am two months into using one of these and love it.
    It is not a plug and play item so be prepared to tinker a little with plumbing to optimize it for your situation.
    A few observations from my experiences:
    a) I found that under 350 gph there was not enough flow to pick up detritus so the paper stayed clean and never "rolled"
    b) At 500 gph the back pressure on the exit was too much so the paper roll turned too quickly.
    c) My perfect flow rate is at 420 GPH. My paper roll is activated every two hours or so and the paper is a nice dark green which is positively reassuring.
    d) The exit water is heavily aerated so I return it to the far end of my sump far away from the return pickup so that the bubbles have plenty of time to be removed before going to the DT. (The long exit pipe explains my high back pressure)

    The unit is nicely fabricated and I found it easy to adjust and am very happy with the purchase.
  • Great concept failed quickly By Ben on 8/11/2016

    I re-plumbed my sump to include this little beauty. I modified the filter tank body for a standard bulk head and it worked beautifully. After 3 full rolls have gone through the system, the motor is no longer strong enough to automatically pull the roll forward. Water then builds up and goes out the overflow. This happens several times a day and manually pulling the wheel and floss forward a couple times a day is not what I bought this filter to do.

    If the motor and unit worked as designed it would be fantastic.
  • Awesome By Joseph on 6/26/2016

    This will be a must have on all reef tanks I set up from now on! You have to get the conversion bulkheads because the metric ones it comes with will not fit standard sized pvc. First off this thing is huge! It will not fit in your sump unless you have a very large tank. The solution I had was to run a pump in the sump to the rollermat via a combination of pvc pipes and vinyl tubing. Make sure you put a ball valve or gate valve in the intake of the pvc so you can adjust flow into the system. Also ensure the return is higher than the sump because it is gravity fed. I put mine on some cinder blocks to elevate it. It's a bit of work to set it up externally but it was totally worth it! When you replace the bulkheads make sure the rubber gasket is on the OUTSIDE of the bulkhead or it will slowly leak. Highly recommend this product, well worth the price!!!
  • it works By David on 6/19/2016

    Plain & simple, this thing works great! it's a little pricey, but not having to change out socks is well worth it to me. I've had this for about 2 months now & it hasn't skipped a beat.
