5 Stage Filtration

  1. Mechanical - The porous foam catches large debris
  2. Mechanical - Dense poly foam filters out fine particles
  3. Chemical - Activated carbon absorbs undesirable odours, colours, and impurities
  4. Biological - Bio-screen blocks debris from entering the biological filtration stage. The micro weave provides large amounts of surface area for better biological filtration
  5. Biological - The biological trickle chamber allows the C-Nodes to have better exposure to oxygen. This allows the beneficial bacteria to quickly reduce toxins such as nitrite and ammonia

Verry good product Review by lester
Does everything it should and does it well. Only issue I have is that when you pull the foam filter out for cleaning, make sure to siphon out that part of the filter before you put everything back together and turn it all back on. If you don't, then everything back there will be pumped into the tank (but the filter will clean it up in time).
