WaterTreats Silica Glass Airstone
WaterTreats diffusers are top quality and made from a solid piece of glass bonded silica in the U.S.A. Uniform fine/medium bubble options are available and allow for dust and dirt particles up to 30 microns to easily travel through which prevents clogging problems and removes the need for extra filters. WaterTreats diffusers have a low air resistance of 0.25 psi and are self weighted. Maintenance is minimal with most applications requiring cleaning at a yearly frequency or less. The cleaning and restoring to like-new condition is easily done by a simple acid bath. With a 2 year manufacturer guarantee, WaterTreats is the best option if you are after top quality performance.
