Aquarium Fish Tank Biochemical Sponge Bio-Filter Oxygen

Sponge filter provides both mechanical and biological filtration. Aerobic bacteria colonize the sponge, providing a bacterial substrate to facilitate the nitrogen cycle. In addition, the sponge traps larger waste particles, mechanically cleaning the water. All hydro-sponge filters are designed for stacking to increase filtering capacity

  • Small size is suitable for 10 to 20 gallons
  • Medium size is suitable up to 40 gallons
  • Large size is suitable up to 60 gallons 


The sponge will need to be rinsed every time it becomes dirty, about once every 2 to 4 weeks. It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water.

After 3 to 6 months’ usage, the micro holes of sponge is gradually clogged by the tiny debris, the beneficial bacteria won’t have as much living space as before.  That’s when the sponge filter starts to lose its efficiency.  So it is also recommended to replace the sponge once every three to six month or when the sponge gets worn out.
