MixAir Ornamental OB1 Weighted Pond Diffuser Aerator Air Stone

Use the MixAir Ornamental OB1 for small backyard ponds, odd shaped alcoves in ponds or in small tanks. Fill the built-in ballast completely with pea gravel before placing it where you want to improve your water. The Ornamental OB1 is a fine bubble diffuser that both aerates and mixes in one efficient device. It is designed to generate dissolved oxygen throughout a water column to accelerate inversion or turnover which keeps water fresh. The OB1 works 24/7 to improve water clarity, stimulate biological activity and provide continuous mixing at a lower power consumption with the benefit of aerating at the same time.
