Optimized water purity The filter mechanism removes contaminants and creates crystal-clear water. Its gentle, biodegradable cleaning action supports species-appropriate living conditions in the aquarium. Perfect filtration performance Special block densification binds powder particles completely, preventing blackwater and creating optimal conditions for fish and plants. Effective dirt binding Selective uptake of harmful impurities prevents deposits. This increases mechanical filtration capacity while protecting filter components from premature wear. Natural ecosystem Maintains the biological balance of the water through a gentle filtration action, protecting fish health and plants from pollutants and supporting healthy living conditions. Key attributes Function: delivers reliable filtration, contaminant removal, and prevention of deposits while preserving beneficial bacteria with a gentle filtration approach. Compatibility: designed for standard aquarium filtration systems. Material and design: block-densified filter media with a biodegradable cleaning action for effective, gentle operation. Performance: reduces particulates, prevents deposits, and supports overall water quality and stability for fish and plants. Use scenarios - New tank setup with visible turbidity or fine particulate matter that needs rapid clarification and stabilization. - Planted aquariums with sensitive species that require steady water parameters and minimal disturbance to the root zone and beneficial bacteria. - Tanks with driftwood or high organic load that tend to produce darker water (blackwater) and require reliable removal of dissolved and suspended impurities.
