Eheim EHFISYNTH Filter Floss, 1L

Mechanical Filter Media works much like a sieve trapping particulate waste as it passes through the material.

EHFISYNTH 1L: A completely neutral filter wool. The fine phenol free structure of this synthetic material traps tiny particles of dirt. It should be loosely placed as the last layer in your filter arrangement. For models 2222, 2224, 2226, 2228 we recommend a special EHFISYNTH pad.

Thought it was going to be a heavier floss from the pic on the box but its the same old floss that you can buy at any fabric store and for as much as this cost you can buy a pillow case full for the same price. But over all this is a good floss.

As can be expected from Eheim, this stuff works great, is easy to replace and pretty cheap for the amount you get. A 2L box is probably about 10 feet of floss once pulled out of the box, probably more actually. Makes the water look great
