ISTA Small Double Sponge Filter


  • High quality sponge foam that assures a greater working life and its porous foam tissue forms large and ideal surface area for bacteria colonisation
  • Easy to install, simple to maintain and low cost to run
  • Driven by air pump to increase oxygen solubility
  • Great for raising fry, breeding, as a hospital/quarantine tank or for keeping delicate species


  • Soak the biological sponge in a cycled tank for an extended period of time before use for quick bacteria colonisation
  • Use tank water when cleaning the sponge as untreated tap water will harm or damage beneficial bacteria
