Sponge filters work by drawing aquarium water through the porous sponge. This provides mechanical filtration by trapping physical debris, and with its large porous surface area provides a home for beneficial, nitrifying bacteria, which break down biological waste into less toxic elements.

  • Fry tanks
  • Betta bowls
  • Hospital/Quarantine tanks
  • New aquarium start up
  • Pre-filter for canisters

In order to keep the filter biologically active, rinse the sponge in a bucket of aquarium water only (NOT TAP WATER - the chlorine in tap water will kill the beneficial bacteria). Squeeze the sponge out several times in the bucket. Discard the used water in the bucket, DO NOT add the dirty water back into the aquarium.
