We have been waiting quite a while for a product like the Theiling Automatic Rollermat. With the Theiling Rollermat 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


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


Plumbing Info

Due to the manufacturer of this product being in Germany the bulkheads that are already installed on the Rollermat 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 Rollermat 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 Rollermat, 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.

Product Questions

Would if be feasible (or advisable) to install a second input - such as for the secondary line in a bean animal installation? I would think you would want both the main and secondary to go into the roller mat, and the emergency to go straight to the sump?
Question by: Larry on Mar 23, 2018, 5:44 PM
Adding a second input to the roller mat is fine, as long as the combined flow rate does not exceed the rated flow rating of the roller mat. Have a great day :)

How do you clean the crap that accumulates in the bottom of the Theiling Roller Mat?
Question by: Dave Niedziela on Nov 11, 2017, 8:07 AM
In almost all containers, sumps, tanks, roller mats, etc will eventually have detritus build up on the bottom. To remove it we suggest just treating it like a water change, and siphoning out the detritus as necessary.

What is the water level max, min and suggested for the roller mat?
Question by: thomas gregory on May 10, 2017, 3:26 PM
Hey there,
The Theiling rollermat is designed to operate above the water level of your sump so that the processed water can freely spill into the sump. There isn't really a min/max water level required, aside from making sure the water can flow freely down and out of the central bulkhead and into your sump.

Happy reefing!

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 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! :-)

How high is the output from the bottom of the unit?
Question by: Shawn on Jan 7, 2017, 2:34 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 on Jan 10, 2017, 2:11 PM
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 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! :-)
Answer by: Randy on Jan 10, 2017, 3:03 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 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.

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 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.

What warranty does it have?
Question by: Emmanuel Becerra on Jul 9, 2016, 2:02 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 on Jul 11, 2016, 12:00 PM
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 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.

Generally how long do the felt cleaning material last before needing to be change?
Question by: Dan on Jun 23, 2016, 10:44 AM
Great question!
Will vary on how much waste it put in however standard is around 2.5 months.
Answer by: Connor on Jun 28, 2016, 3:18 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 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.
