The OASE EcoFlow filter foam is the ideal replacement filter sponge for OASE internal filters in the EcoFlow series. It provides mechanical pre-filtration and reliably traps dirt particles from the aquarium water. At the same time, the foam structure offers a surface area for beneficial filter bacteria to colonize, thereby supporting the biological filtration performance of the internal filter. The filter foam is precisely tailored to the EcoFlow filter modules and can be easily replaced during regular filter maintenance. Replacing the filter foam in a timely manner or cleaning it gently helps to maintain the long-term filter performance of the OASE EcoFlow internal filter. The condition of the filter foam should be checked regularly, especially with a higher stocking density or visible contamination. The OASE EcoFlow filter foam is suitable for the EcoFlow 60, EcoFlow 100, EcoFlow 150, and EcoFlow 200 models. OASE EcoFlow Filter Sponge+ Original OASE replacement filter sponge for EcoF
