ISTA Small Double Sponge Filter


  • Quality sponge foam assures greater working life and its porous foam tissue forms large and ideal surface area for bacteria colonisation
  • It is easy to install, simple to maintain and low cost to run
  • Driven by air pump to increase oxygen solubility
  • Great for raising fry, to breed, as hospital tank or keeping any delicate species


  • Soak the bio 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
