Purigen is an exceptional synthetic adsorbent that stands out from conventional filtration products. Rather than being a blend of ion exchangers or adsorbents, it is a distinctive macro-porous synthetic polymer designed to eliminate both soluble and insoluble impurities from water at a rate and capacity that surpasses all other competing options by more than 500%. Purigen effectively manages ammonia, nitrites, and nitrates by extracting nitrogenous organic waste that would otherwise release these harmful substances. KEY FEATURES: Unmatched organic removal capacity Enhanced efficiency due to its extensive surface area; both spherical and macroreticular Assists in controlling ammonia/nitrite/nitrate levels Color shifts as it reaches its limit; can be easily regenerated DIRECTIONS: Rinse thoroughly before use. It should be placed in a fine mesh (180 micron or less) filter bag like Seachem's The Bag. For optimal performance, position Purigen to maximize water flow through it. It can be utilized in a canister filter, media chamber, box filter, or any high-flow section of a trickle filter. Each 250mL can treat up to 1,000L (250 US gallons) for as long as six months. A significant change in the color of the beads to dark brown or black indicates exhaustion.Expires on 01 Jul 2030

Matrix is an advanced biomedia with high porosity, designed for effective biofiltration to eliminate nitrogenous waste. This inorganic solid measures approximately 10mm in diameter. KEY FEATURES: Exceptional biofiltration capacity Regulates ammonia, nitrite, and nitrate levels Extensively porous - vast surface area (>~700 m2/L) Supports a range of aerobic and anaerobic bacterial species DIRECTIONS: For every 200L (50 US gallons) of water, use 250mL of Matrix. This product can be utilized in any filter type, with optimal results in canister filters. Its size is suitable enough that a filter bag is typically unnecessary for most uses.Expires on 19 May 2030

The EHEIM SUBSTRATpro+O2xygen - a filter medium that revolutionises biological water treatment. This latest development, based on the tried and tested SUBSTRATpro, combines first-class materials with stateof-the-art technology. The secret behind the extraordinary effect of EHEIM SUBSTRATpro+O2xygen lies in the gemstone mineral tourmaline it contains. Thanks to its unique pyroelectric properties, it generates electron-activated oxygen (super oxygen O2-) on contact with water, which optimises the oxygen supply in the filter substrate and creates ideal conditions for filter bacteria. This stimulates the metabolic processes in the aquarium and activates the vitality of fish, plants and the entire aquatic ecosystem. Efficient removal of pollutants - the spherical structure enables a high bulk density and makes optimum use of the available filter space. With a porosity of 45 %, the ceramic material provides a huge surface area for beneficial microorganisms. The combination of a large colonisation surface and activated oxygen breaks down pollutants faster and more efficiently - for crystal-clear water and a healthy ecosystem. Durable & sustainable - the filter material is specially heattreated at over 1,000 °C, which makes it particularly stable and durable and guarantees outstanding resistance. It is pHneutral, reusable and suitable for fresh and salt water. Advantages of the EHEIM SUBSTRATpro+O2xygen High-quality material: ceramic filter mass made of sili-cates and tourmaline Innovative technology: Tourmaline produces electronactivated oxygen (super oxygen O2-) for efficient oxygen supply High porosity of 45%: for an above-average settlement area of filter bacteria pH-neutral: Does not affect the water chemistry and ensures a stable, healthy aquarium climate Fast degradation of pollutants: Allows extremely fast biological degradation of impurities Promotion of metabolism: Activated oxygen strengthens fish, plants and the entire ecosystem Durable and robust: Burned by extreme heat (over 1.000°C), the mate-rial offers exceptional durability Can be used several times (rinse carefully for cleaning) Suitable for fresh and sea water
