    Extra solids filtration for the DIY'er. A good biofilter needs a lot of surface area with open spaces between for good aerated water flow. A high surface area is useless if the passageways are so small that water flow cannot penetrate.  The 23" Filter Brush is great solids filtration for any shaped filtration tank.  Line up many of them together in rows to create a wall of brushes to collect large fish solids on the bristles and let clean water pass through.
