Replacement Biotec Foam Blue 12/40000/90000 Designed to work hand in hand with the Oase Biotec Screenmatic Pond Filter and the Oase Biosys Pond Filter Sets.

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.Each pack contains:42893 = 1 x Red & 1 x Purple42895 = 2 x Blue42894 = 1 x Red & 1 x Purple42896 = 2 x Blue
