Bacto-Surge Biological Action Filters are air-driven sponge filters (air pump not included) which offer superior mechanical and biological filtration of your aquarium water. The highly porous sponge contains extreme surface area and thousands of microscopic pores where aerobic bacteria, hydrated with oxygenated water, can grow and flourish.

  • Highly porous sponge maximizes bacterial action
  • Increased surface area offers maximum bacteria colonization
  • Soft sponge material is easily cleaned
  • Polyether foam for longer life
  • Uplift tube and air diffuser combination provide maximum lift and won't easily clog
  • Other uses: polishing filter for canister filter applications, hang on filter applications or uplift tubes of undergravel filters.
  1. Before installation, soak the sponge block in aquarium water for at least five (5) minutes.
  2. To clean sponge block, always rinse with water taken from your aquarium. Do not use tap or hot faucet water as this can damage the sponge block and impact bacteriological action.
  3. When re-installing the sponge block, submerge in aquarium water and squeeze gently to remove all trapped air inside the microscopic pores. This allows the sponge block to operate properly.
  4. For optimum performance, replace the sponge block every six (6) months. Allow the new block to soak in your aquarium water for a minimum of two weeks before installation to allow it to colonize with nitrifying bacteria.
  5. The Bacto-Surge Sponge Filter requires a minimum of 30 days of use to operate peak performance. Care should be taken during this time to monitor your ammonia, nitrite and nitrate levels as the aquarium progresses through the nitrogen cycle. ClorAm-X can help control ammonia toxicity during this period.
