My biofilter Q requiered is 100 gpm, however that is a lot of flow rate for my tank, so I bypass 70% of the water to a degass unit and 30 % to the fish tank. The water comes from the biofilter, in the top part is a venturi, that is where I inject the O2, so 30% of water goes into the tank with aprox 11 mg/l of O2.
I have other picture with a O2 saturator we design at the lab, i will upload it later today. Hope I answer your question.

I am intrigued by how you have the O2 saturator plumbed into this system. Could you please explain how it is plumbed and the system working??
