What to Look for Aquarium Filters for Sale

Using filters that work with your saltwater aquarium’s filtration system is crucial. Bacteria and algae thrive when you don’t have proper filtration in place. There are three types of filtration:

  • Mechanical/Physical: This removes debris from the tank by running the tank water through a felt sock or pad.
  • Chemical: This lowers levels of chemicals like phosphates and nitrites that can grow toxic at high levels. This is done by running water through filtration media like activated carbon, which bonds with those harmful chemicals and removes them from the water.
  • Biological: The removal of waste or bad bacterial growth. This is done by good bacteria, which convert harmful chemicals into harmless ones.
