What makes ABI Diffusers different?


Maximize Aeration Performance with ABI Stainless Steel Diffusers

Blows All Others Away!

Engineered to outperform all other diffusers, including other membrane diffusers


 What Makes Our ABI Stainless Steel Diffusers Up To 75% More Efficient Than Other Diffusers?

AquaBio Six-Shot


  • Highest turnover/circulation rate per cfm
  • Highest oxygen transfer efficiency (SOTE) per cfm
  • More surface area moves more water
  • Flow through design moves more water
  • No Underwater Degradation
  • Less flow interference (areas blocking water)
  • Less back pressure = Increased CFM output
  • Less cleaning
  • Thick wall membrane creates fine micro-bubbles
  • Interchangeable Diffuser Membranes
  • 15 year warranty on all stainless pieces!
