Integrated automatic self-priming for quick and easy filling of the canister filter

4 heavy duty super locking clips for tight closure of the pump head onto the canister
Integrated safety handle prevents accidental opening while carrying

Easy to use quick release two stage hose adapter, Only disconnects once flow control level is placed in the off position.

Where precision is paramount, high tech ceramic material is the instrument of choice. Only EHEIM;s shaft and bearing sleeves are made of space age high performance ceramic. Ultra quiet, resistant to heat, abrasion, chemical and biological substances as well as an extremely long service life

The new convenient pre-filter with easy access just under the pump head traps dirt at the top of the filter, making regular maintenance easier. Significantly extends intervals between biological media cleaning. Simply rinse pre-filter pad (blue) and change the fine filter pad (white); the biomedia in the media baskets remains undisturbed

HOW IT WORKS: High Capacity Multi-Stage Filtration:

Aquarium water enters the filter through the intake tube and then flows downwards to the new pre-filter tray. Reversing direction, water then flows up through the first stage prefilter foam; trapping the majority of the large debris at the top.

Stage 1:Mechanical Pre-Filter

Easy Access just under pump head at top design
Traps mechanical debris making regular maintenance easier
Significantly extends the time between cleaning intervals of biological filter media
Simply rinse pre filter and change final stage filter pad when needed
Bio-media in lower baskets remain undisturbed

The water is then pulled down an internal tube to the bottom of the canister where it is dispersed and is suctioned up through the second stage multi-purpose media baskets, at which point it passes through, with the typical EHEIM set up, the biological layer or media EHEIM Substrat pro. This media contains thousands of square feet or nitrifying bacteria which biologically breaks down aquarium toxins.

Stage 2: Multi-Purpose Media Baskets — Biological, Chemical or Mechanical

For most aquatic environments
Media baskets containing high efficiency biological media, provide the healthiest, clearest aquarium water.
With regular maintenance of pre-filter and fine white filter pad, this setup lets you go up to one year without having to maintain your biological media baskets.
Multi-purpose media baskets permit customization of your filtration setup. This is ideal for the serious aquarist.

In the third stage, water is pulled through the fine white filter pad, performing the final water polishing by trapping the finest dirt particles. The clean filtered water then flows back out into the aquarium.

Stage 3: Final Water Polishing Filtration

Traps even the finest particles before allowing the clean water to flow back into the aquarium.

  1. Good morning I am studying and reviewing and studying your video. I would like to do the same thing with the tank that we have. I have a 55 gallon tank. One painted turtle,four goldfish. And two algae eaters.

  2. I know this is an older video but I have a question. This is the same filter I have. In a move the hose was lost. Can you tell me if the 16/22 mm of the hose is ID or OD?

  3. iv owned a lot of eheim n fluval filters over the years and the fluval may look nicer and may have more flow rates but the eheims last theres no by pass they don't break iv had troble with fluval filers the 06s can leak the u,s bits break off the c,s are good hang ons iv never had a proble with non of the 2 eheim 2213s iv got te oney eheim product iv ever had problems with was with a jager heater that sticks on out o the box but I put tat down to factory bult mistakes every heater can fail even new isn't ideal but I agree with joey on his eheim pro 3 ill be better than the fxs no bypass more media relieable I like the fx4 n 6 they look nice great flow but mediadwell times are more important to me than flow and that's where eheims win hands down
