Active Aqua air stones are an ideal way to add oxygen to your hydroponic growing system. Their micropore design energizes the growing solution as it aerates and circulates nutrients. These flexible stones bend into any shape to deliver air where you need it most, and also: 

  • Extend the life of your nutrient solution
  • Help keep roots healthy
  • Promote exceptional growth
  • Infuse your reservoir with dissolved oxygen
  • Create less back pressure than traditional air stones
  • Choose from three versatile flexible stone sizes.

This one is 48 inches/four feet in length.

Customer Reviews

Insufficient use at this time Review by The Old Man
This unit appears to work very well but we have only had it turned on in one tank so far. Can't give a full review until it has been used longer as it may clog uo with a full load of bait fish.
