Filter Maintenance: Maintaining your filter is best done while you are changing your filter media. Rinse the filter canister and the two lattice screens with water and remove any dirt residues. Before the pump head is replaced, check the rubber o-ring. If it is worn, it should be replaced immediately. If the o-ring is not worn, it should be moistened so that the pump head can be pressed down without difficulty. The water inlet of the canister should be cleaned with a cleaning brush. At longer intervals (every six months or when build up of debris is seen), the hose system should be cleaned. The pump of your EHEIM filter also requires some regular maintenance. Remove all parts carefully and clean all parts with a mild dishwashing soap and rinse thoroughly with water making sure that no soap remains. Clean the cooling pipe and the impeller chamber with a brush. Replace all parts in reverse order of dissemble. For model 2213, while replacing the cooling pipe shaft, ensure that it is pushed in until it is flush and locked into place. IMPORTANT: if your pump is extremely dirty and the impeller and associated parts are hard to remove, soak the complete pump head in warm water and mild dishwashing soap overnight. You should never force the removal of these parts, as they are fragile.

Filter media: Filter media fulfill various functions - mechanical, biological, adsorptive and chemical filtration. They remove dirt particles and suspended floating matter from your aquarium and ensure the biological conversion of toxic waste or the chemical alteration of the water. Ideal water conditions very much depend on the correct use of filter media.

EHEIM filter pads are used to separate the different filter media layers in standard filters.

EHEIM filter cartridges made of special foam materials provide a large filter surface. They can be changed in a few simple steps and after their "running in" time they not only function mechanically but also biologically. EHEIM active carbon cartridges are also excellent for adsorption.

EHFISYNTH filter pad for mechanically fine cleaning, especially for EHEIM professionalexternal and thermo filters.

Media Maintenance: Your filter media needs to be cleaned every 3-6 months. You should change 1/3 to­ 2/3 of the EHFISUBSTRAT every 6-12 months. The EHFISYNTH pad should be changed with every cleaning and the EHFIFIX pad should be changed when it becomes flattened or every year.

Filter Media Purpose
Ehfisynth A fine mechanical filter material made of phenol free neutral filter wool that traps tiny particles of dirt.
Ehfisubstrate To create biologically sound water, as found in nature, you need a large surface area for bacteria to grow on. With an amazingly large surface area of 450 m2/liter ehfisubstrate undeniably offers the ideal conditions.
Ehfifix This mechanical filter pad is placed between Ehfisubstrate and Ehfimech to trap debris and acts as a divider.
Ehfimech This coarse mechanical filter media has a hollow ceramic design to create eddies which disperse the water into many paths and traps large debris while creating an even flow of water for subsequent layers.


Eheim Classic Canister Review:

By Kmuda


The Eheim Classic canister filters are the original "Canister" filters and little has changed over the decades since their first release. Some may see this as applying outdated technology. I see it as "if it ain't broke, don't fix it", as these are perhaps the most dependable and efficient filters on the market. Sure, other filters have cooler stuff (bells and whistles) and convenience features, but these added features introduce added cost and complexities into the equation while not really adding much (if anything) to what we actually need a filter to do, which is filter the water. That is what these filters do as well, if not better, than any filter on the market. Their beauty is in the simplicity of the design.


  • Perhaps the most dependable filter on the market. There are examples of this filter being in constant use for over 20 years.
  • Filter is designed to provide the most efficient filtration possible. The filter volume, hose sizes, and flow rates are engineering specifically for this purpose
  • This filter has been in manufacture for decades, spare parts are readily available.
  • Each model of filter comes complete with all necessary media. Eheim media is of the highest quality. There is no need to incure the added expense of improving upon it.
  • Zero Bypass - Dirty water enters from the bottom and exits from the top. A very simple design concept which ensures there is no bypass.
  • All Classic filters now come with quick disconnects to simplify maintenance.


  • Flow rates are lower than other comparable filters within this price range. While this really has no bearing on biological filtration, it does limit mechanical filtration.
  • Bright green tubing can be considered an eyesore.
  • This filter does not have filter trays for easy removal and maintenance. While some find this an inconvenience, I do not. Use of large filter bags to house the biomedia will make removal of media for cleaning as easy, if not easier, than with standard filters. In addition, trays take up filter volume which can otherwise be used by added media. Filter trays also introduce bypass issues.
  • No priming button. I've never found this to be an issue as you only have to prime it once, during initial setup. From that point forward, if following the proper procedure during maintenance (discussed later), the filter will self prime.
  • In line quick disconnects can be a little more difficult to work with than are valve blocks found on more modern and complex filters, but it should be noted that it is those "valve blocks" that are responsible for most leaks on the more modern designs.

Other information:

  • To simplify maintenance Purchase a 12"x15" media bag to hold the biomedia.
  • Use the default media, stacked as specified, with only the biomedia in a media bag.
  • The stock "Carbon Pad" can be used without concern but there is no need to replace it. I use mine as the final layer of the filter to ensure stands of floss material from the "polishing pad" do not get pulled into the impeller.
  • To conserve cost, plain ole' polyester filter floss can be used instead of the Eheim Fine Media pads, but you will want either a layer of blue bonded padding (cut to fit) or the carbon pad (I've been using the same ones for years) as the top layer to prevent the floss from getting wrapped around the impeller.
  • I believe Eheim overstates the filter capacity of their filters, at least when it comes to housing large cichlids such as Oscars. I would not feel comfortable with a single 2217 or 2215 on anything larger than a 55 gallon tank, a 2213 on anything larger than a 30 gallon tank.
  • To prevent air from being in the filter when you prime, do not connect the outflow tube. Leave it disconnected (from the other section of the tube). Open the disconnect valves on both the inflow (which should be connected) and the outflow (which should not be) and hold the outflow over a bucket. Allow the canister to fill and then allow water to exit the outflow (which is being held over a bucket) until the water runs smooth (no gurgles, bubbles, etc...). Then engage the disconnect shutoff (on the outflow being held over the bucket) and screw it back onto the other half of the return tube. Make sure all valves are open, and plug the filter back up. 

Recommended Maintenance Procedure:

  1. Fill two buckets with tank water
  2. Engage shutoffs on both the outflow and inflow tubes
  3. Unscrew both quick disconnects and carry the canister to a sink.
  4. With the canister sitting on the cabinet, place the inflow tube (the bottom one) into or over the sink and open both quick disconnect valves. This will cause the filter to backflush, draining into the sink.
  5. Once the canister is drained, unhook and remove the motor head.
  6. Remove the top layer media (should be polishing pad and carbon pad or appropriate substitutes) and place in the sink.
  7. Remove biomedia bag and place into one bucket of water (this is your "dirty water" bucket).
  8. Either dump the biomedia into the bucket or open up the bag (depends on how dirty the media is).
  9. Using your hand, swirl the biomedia around in the bucket to rinse off gunk that has built up on the media.
  10. Once the media is clean, place it back into the media bag (if it was removed) and move the media bag into the second bucket of water.
  11. Remove the course blue sponge from the canister and place it into the bucket of "dirty water", squeezing and rubbing it clean, then move it into the second bucket of water.
  12. Dump the Eheim Ehfimech from the canister into the bucket of "dirty water". Using your hand (or something to stir with) mix up the media, causing the gunk to dislodge.
  13. Place the canister in the sink and rinse it clean.
  14. On the motor head, carefully remove the impeller cover, then carefully remove the impeller
  15. Rinse the impeller clean, scrubbing it with a toothbrush
  16. Using a rag, filter brush, or q-tip, clean the impeller housing.
  17. Carefully, place the impeller back into the motor head and replace the cover
  18. In the sink, rinse the top layer carbon pad (or appropriate substitute) clean.
  19. Retrieve the Ehfimech from the bucket of dirty water, placing it back into the canister
  20. Retrieve the Sponge from the second bucket and place it back into the canister
  21. Retrieve the biomedia bag from the second bucket and place it back into the canister
  22. Replace the polishing pad (or appropriate substitute), placing the new pad into the canister
  23. Retrieve the carbon pad (or appropriate substitute) from the sink placing it back into the canister
  24. Place the motor head back onto the filter and clamp it down, ensuring you engaged all clamps.
  25. Carry the filter back to the tank.
  26. Screw the inflow quick disconnect back up to the inflow tubing remaining on the tank.
  27. Hold the outflow tube over a bucket
  28. Open the quick disconnect valve on the inflow
  29. The filter will start to refill. Continue holding the outflow tube (that you have not yet reconnected) over a bucket of water until it runs smooth (no gurgles, burbs, or bubbles).
  30. Close the quick disconnect valve on the outflow (that you are holding over the bucket) then screw it back up to it's counterpart that is still on the tank.
  31. Open the disconnect valves on the outflow.
  32. Plug the filter back up and it will crank right up.

2262 = Priapism in a box! :woohoo:

Speaking of Viagra...
I put some in my boss's coffee just to see what would happen.

He just got taller!

Tom, I have not had the opportunity yet to determine if the heart attack, subsequent surgery, and resulting medications left me in need of Viagra (it's an old site joke people)......... but purchasing a 2262 just may serve the same purpose. :whistle: :lol:

I am planning on purchasing the grand daddy of the classic line, the 2262.
Last week I received 20 liters of Matrix for it (the thing holds 18).
A pump that does 900 gph through that much media... makes my mouth water.
