The essential shield for your filter. These EHEIM MECH hollow ceramic rings stop large debris as it enters the filter, protecting your delicate biological mass. They also act as a "breeding ground for bacteria".

Thanks to their tubular structure, they create a vortex that disperses the water evenly, ensuring a constant flow without clogging. The material is washable and infinitely reusable.

🛡️ Your filtration bodyguard

One of the common mistakes in fishkeeping is neglecting the pre-filtration stage. If dirty water goes directly onto your fragile bacteria, they suffocate and die. EHEIM MECH solves this problem permanently. Unlike foams that clog quickly, these non-porous ceramic rings mechanically capture large dirt particles (food scraps, plant debris, excrement) as soon as they enter the filter.

By retaining these heavy materials at the bottom of the filter, they ensure that the water rising to the upper levels is already 80% free of visible pollution.

🌪️ Hydrodynamics designed to prevent clogging

The shape of these noodles is not accidental. They are hollow cylindrical bodies that act like miniature whirlpools. When water passes through this ceramic layer, it is forced to disperse in all directions.

This turbulent flow breaks down preferential flow paths and ensures even oxygenation of the entire filter. The major advantage of smooth ceramic over lava rock or porous media at this stage of filtration is its partial self-cleaning capability : dirt slides off the surface and falls to the bottom of the tank, allowing water to flow freely.

🤓 Durability and maintenance : A lifetime investment

The EHEIM MECH is made from a ceramic fired at very high temperatures, which is completely chemically neutral. It does not release any substances into the water and is suitable for both freshwater aquariums (even the most delicate ones like Discus tanks) and saltwater aquariums.

It's an indestructible material. Where foams crumble and need replacing, these noodles simply rinse with warm water (even under the tap for this specific medium, as it doesn't contain bacteria) and can be reused indefinitely. It's the most economical filter medium in the long run.

FAQ

Absolutely. The term "ceramic noodles" is a universal standard in aquariums. EHEIM MECH can fill the bottom basket of any external filter (Oase, JBL CristalProfi, Fluval, Tetra) or even be placed in a net for a saltwater sump. Its hydrodynamic efficiency will improve the performance of any setup.

Almost never. EHEIM ceramic is of exceptional quality and does not degrade in water. As long as the rings are intact, they retain 100% of their mechanical efficiency. You will only need to buy a new box if you lose any during cleaning or if you upgrade to a larger aquarium.

Unlike bio-balls, which require careful handling, the EHEIM MECH is robust. Since it doesn't serve as the primary bacterial substrate, you can rinse it vigorously under tap water (at room temperature) to remove all the accumulated sludge. This cleaning should be done as soon as you notice a significant drop in your pump's flow rate, generally every 3 to 6 months depending on the load of your aquarium.

It's a question of filtration order.EHEIM MECH (This product) is purely mechanical : its smooth surface serves only to trap large physical debris without clogging. BIO MECH is a hybrid that contains some porosity for bacteria.

The SUBSTRATpro (beads) is purely biological: it's an ultra-porous sintered glass designed to house billions of bacteria. The ideal order is always : MECH at the bottom (to clean), then SUBSTRATpro at the top (to purify).
