Oase Biotec 5 / 10 / 30 Replacement Foam (Red)
Replacement red filter sponge for the BioTec 5, 10 & 30
The essential part of a filter is its sponges. Red sponges provide fine filtration by trapping small dirt particles at a medium water flow rate, effectively cleaning pond water. These sponges also offer a habitat for tiny bacteria that help convert harmful substances into harmless ones, and then into natural gases. Along with blue sponges, they ensure the filter performs efficiently and maintains clean water
