Designed to work hand in hand with the Oase Biotec 12, 18 and 36 these compact filter foams work together to make a strong filtration system that keeps out all of the grime, waste and debris.
The filter foams are available in red and blue versions each a different filter grade. The blue sponges are coarser and will trap the larger particles of waste, whereas the red are much finer in order to trap the small pieces. Thanks to the unique 'screenex' built in to the unit, large particles are strained away before they hit the filter foams, which prolongs their life and lowers the amount of maintenance needed.
- Red = fine grade foams
- Blue = coarse grade foams
One supplied, simply add the amount of each foam you need to the basket.
