Can you set the spray bar so that it is just at water level? That way, the water from the filter return is gently rippling the surface of the water; this is the ideal amount of surface agitation you want to have to prevent excessive CO2 off gas (diffusion).
I redid it so it is about 1/2 above the surface. I will go buy some adapters tomorrow so I can adjust the bar lower. With the holes drilled on the returns the streams are somewhat strong & usually the remedy to this would be bigger holes but that is not an option...too scared a shrimp might find his way in. So aside from me needing the spray bar right at the surface would the jet like stream affect anything?
