The summary
- What you receive: EHEIM MECH ceramic noodles, loose, in 1, 2 or 5 litres.
- What they do: they churn the water as it enters and make the larger particles drop out.
- Where they go: right at the bottom, at the first point of contact with the dirty water.
- How much effort day to day: a rinse when the flow slows, then they go back in their place.
Hollow ceramic pieces that trap large particles at the filter inlet
The EHEIM MECH ceramic pre-filtration noodles are hollow bodies that fill the first basket of the filter, at the water inlet. They create turbulence in the flow so that coarse particles (food, plant debris, waste) settle out, which delays clogging. Washable and reusable, they are sold in 1, 2 or 5 litre packs.
These hollow EHEIM MECH ceramic pieces fill the first basket of your filter, the one the water passes through as it enters. There they trap leftover food, plant debris and waste before these particles reach the fine media and the biological stage, so a filter set up this way clogs more slowly and needs opening less often.
🌀 The turbulent flow
As soon as it enters the filter, the water is made turbulent by these hollow cylinders: it disperses in all directions instead of running straight through, loses speed, and the heavy particles it was carrying drop to the bottom of the tank. This is induced settling, which explains why a layer of noodles clogs much more slowly than a sponge placed in the same spot. You notice it at the first maintenance, since the dirt ends up at the bottom of the tank instead of being trapped throughout the media.
What settles here
Leftover food, plant debris and waste, that is, everything that can be seen with the naked eye in the tank.
What carries on its way
Fine particles and dissolved substances get past this stage and are dealt with by the filter's following baskets.
♾️ A washable, reusable filter mass
The ceramic is washable and reusable several times over. Where a foam crumbles and eventually has to be replaced, these hollow pieces are rinsed and then put back in place. As they do not carry most of the filter's nitrifying colony, rinsing them does not require the precautions of the biological stage: you rinse them in clean water, tap water included, without compromising the balance of your tank. The article on cloudy water in aquaponics details what each stage of the filter actually retains.
Always in the first basket the water passes through
Do not place these noodles above your biological media: they would take up the volume of a basket without protecting anything, since the water would already have passed through the rest of the filter. Nor should you rely on them to clear cloudy water, as they trap visible particles and let the finest ones through, which are dealt with by the later stages.
Sintered quartz beads for the next stage
Once the inlet is fitted, the biological stage receives water free of coarse particles, and its media stays irrigated for longer. EHEIM SUBSTRATpro biological filtration beads then fill the middle baskets and provide 450 m² of colonisation surface per litre. This way you complement the first stage with the one that converts ammonia and nitrite.
📏 How much to allow for
The quantity is measured against your filter's intake basket, not the volume of the tank: fill the basket with water, pour it into a measuring jug, and you have the volume of noodles to allow for. One litre weighs approximately 840 g, which makes it possible to split a pack using kitchen scales. The 5-litre bucket is intended for large external filters and for the settling chambers of a pond or aquaponic system, where the first stage has to hold back a heavier load of particles. These are the same particles that, without pre-filtration, end up clogging the beads and the biological media placed further along the system.

Which filter media should you start with?
Three media sold in the same volumes, only one of which works at the water inlet.
What clogs first is not always what you replace
A filter that clogs within 2 weeks lacks a pre-filter placed before the foam.
