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.

  • 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.
