Oxygen Shields are made out a recycled rubber polymer and are designed for years of operation with minimal maintenance. Each Oxygen Shield diffuses air at around 3000 microns or 3 millimeters in diameter. Oxygen Shields come in 5 different sizes and fit up to 70 gallon tanks. The beauty of these manifolds is the low diffusion rate needed to fill the Shield.
Revitalizer has been formulated specifically to clean our line of Micro-Pore and Oxygen Shield air diffusers. Simply soak your stone or shield for a few hours; rinse clean and your Micro-Pore and Oxygen Shield diffusers will continue to work like new for many years.
