The EHEIM MEDIA SETs come with both fine and coarse filter pads, as well as mechanical and biological filter media.EHEIM filter media is designed for high efficiency, developed in our own lab, crafted from top-quality raw materials, and consistently tested to ensure they are free from contaminants.These fine and coarse filter pads are essential for mechanical and biological filtration.The porous material absorbs water evenly while capturing both large and small dirt particles. Following a brief startup phase, beneficial bacteria that promote the effective biological breakdown of harmful substances settle into the uniquely structured foam.The fine and coarse filter pads can be reused multiple times. For cleaning, simply rinse and gently squeeze them to preserve the bacterial cultures.Porous material effectively captures both large and small debrisCreates optimal conditions for bacterial colonizationCan be reused several timesCleaning is as simple as rinsing and squeezingEHEIM MECHPrefilter material composed of hollow ceramic rings designed to catch larger dirt particles.As water enters the filtration process, it flows through the hollow ceramic rings, allowing larger debris to settle at the bottom. The prefiltered water then moves through the remaining filter layers. EHEIM MECH is straightforward to clean and can be reused.Prefilter material for capturing larger dirt particlesMade from hollow ceramic ringsSimple to cleanReusableCompatible with both freshwater and marine environmentsEHEIM SUBSTRATproThis optimized bio-filter medium ensures excellent volume utilization, extended intervals between cleaning, and superior decomposition efficiency.SUBSTRATpro is made from pearl-shaped sintered glass.

Aquarium Bio Filter Media Plastic Bio Ball The biological ball serves as an excellent filter medium, suitable for drip filters, nitrate filters, and large-scale aquaculture filtration systems. With its thoughtfully engineered design, it promotes even water flow and prevents clogging. These bio balls can be effectively positioned in the upper filter, at the bottom of the tank, in filter tanks, lateral filter tanks, or even in external barrels. Bio balls are specifically designed to enhance the surface area for beneficial bacteria to thrive within your pond filtration system. They offer a greater surface area per cubic foot compared to traditional lava rocks. The biological filter plays a crucial role in maintaining your pond's filtration efficiency. By substituting lava rocks in your biofalls filter with bio balls, you will significantly boost the biological filter's capacity, thereby enhancing your overall filtration system.

EHEIM AKTIVHighly efficient active filter carbon - particularly essential following medication treatmentEHEIM AKTIV is specially acid-washed and activated to ensure optimal water absorption (active surface area of 1200 m²/g). This activated carbon rapidly binds chemical contaminants such as pesticides, medication residues, and other unwanted substances, storing them in significant amounts. Consequently, your aquarium water becomes crystal clear. It is especially crucial to utilize this product after administering medication to the aquatic inhabitants.EHEIM AKTIV should be utilized for a limited duration (approximately 4 weeks) before being removed or replaced.Within the filter's layered structure, EHEIM AKTIV is positioned directly after the mechanical filter media (such as EHEIM MECH or MECHpro) and the biological media (like SUBSTRATpro) within the provided net bag.Activated carbon for optimal adsorptionQuickly binds chlorine, pesticides, and various other chemical substancesIdeal for use following new installations or medication treatmentsRecommended for limited use only (around 4 weeks)Compatible with both freshwater and saltwaterAdsorptive filter mediaAdsorption refers to the accumulation of substances (in contrast to absorption). Adsorptive filter media consist of materials designed to extract harmful elements from the water and bind them. This includes chlorine from tap water, medication residues, or traces of cleaning products, pesticides, dyes, and more.Tip:Limit the use of adsorptive filter media to a few weeks. Since harmful substances merely adhere to the surface, they can potentially re-dissolve over time and re-enter the water. Therefore, regular replacement is essential. Typically, adsorptive filtering is only required during the initial setup phase of the aquarium or subsequent to medication usage.

Aquarium Bio Filter Media Plastic Bio Ball The biological ball serves as an excellent filtering medium, perfect for use in drip filters, nitrate filters, and extensive aquaculture systems. Its scientifically designed structure allows for efficient flow separation, preventing any clogs in the biological ball. These bio balls can be positioned in the upper filter, the bottom of the tank, the filter tank, lateral filter tank, or the outer barrel. Bio balls are designed to enhance the surface area available for beneficial bacteria to thrive in your pond filtration system. Compared to lava rocks, bio balls offer a significantly larger surface area per cubic foot. A biological filter is a crucial component of your pond filtration setup. By swapping out the lava rock in your biofalls filter with bio balls, you will boost the biological filter's capacity, leading to an enhanced filtering system overall.
