Use the MixAir Stone Replacement SRB6 diffuser in ornamental water gardens and small tanks to improve water quality. It is also an ideal replacement for ceramic stones.

The Stone Replacement SRB6 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. It features 6 inches of active aeration membrane, with a total length of 8.5 inches. Connects to your system with a 1/2-inch FNPT fitting.

The SRB6 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.
