A second aerator close to shore will still register 5.5psi with both diffusers operating one deep one shallow. . Try it and see. Operating at 4.5 psi and 5.5 psi will not make a big difference in the life span of the rotary vane. Running at 8hrs/night from May to November, it might shorten the life of the motor by 2-3 yrs of the total 35yrs. Your 0523 rotary vane is running at 1/2 capacity at 5psi. Vanes (rebuilds) will need to be changed 1-3 times in that 35 yr period.
