AQUI-S® Freshwater & Seawater Air Stones

AQUI-S® Air Stone Stones are easy to install, simple to operate, and offer an effective solution for maintaining dissolved oxygen concentrations in both freshwater and seawater tanks.

Applications AQUI-S Air Stones

  • Aquariums
  • Fish tanks
  • Fish farms
  • Hatcheries
  • Live transportation

AQUI-S® Air Stones are designed to operate with low pressure air pumps and blowers. They produce medium size bubbles that are optimal for gas absorption by the water but do not irritate the gills of the fish, as can occur with fine bubble oxygen diffusers.  The silica material is proven to be sturdy, durable and allows for easy cleaning and low maintenance.
AQUI-S® Air Stones are a cost effective solution to aeration.
