After reducing my CO2 injection from 11psi down to 6psi, I have no micro bubbles this morning. And the CO2 has been on for 3 hours before the light comes on. However, my CO2 level was only 28ppm the most. Not 35ppm that I was hoping for. So, I upped the psi to 7-8 psi. Micro bubbles are extremely minimal and the CO2 is around 38ppm by the end of the light cycle.

I'm thinking that he means to bypass the water so that less is flowing through the reactor. This way you don't have to choke the pump and risk damaging it. It would give you more dwell time to dissolve the co2.
as currently i am trying to have only single return to the tank, with the 2x Y splitter i should be able to split and combine the output while regulating the flow on the split to cerges reactor, with the help of the ball valve on the cerges output, before the 2nd Y splitter to combine the flow (same principal to regulate canister filter output on the output line rather than input).
I am not sure whether this make sense ... or if the ball valve should be put on the 1st Y splitter, right before input to cerges.
Ball Valve 1 is on input line for cerges
Ball Valve 2 is on the output line for cerges
i am thinking currently to use Ball valve 2 to regulate flow passing through cerges.
Similar approach is being used on external water heater being used on the pool, the flow goes to the heater (in this case cerges) need to be slower in order to heat properly (in this case to disolve the co2 properly), the bypass line is to let the excess flow through while the flow to the heater line is regulated with ball valve.
with this, the filter flow rate is maintained (not being reduced as if only single ball valve without splitter and no bypass line).

I'm no hydraulics engineer here, but I suspect that everything in that "circuit" will flow right through the bypass hose and ignore the cerges reactor completely. If it were me I would put the ball valve #1 on the bypass hose after the Y to the reactor, and contol the bypass flow that way. That would eliminate the need for ball valve #2 and assuming all the tubing is the same diameter would give you what you're after.
i am looking at following water heater concept, and it seems consistent with your thought on the ball valve #1 on bypass line.
Also there is a check valve involved on this approach, to prevent back flow to the water heater.
On the right, I might found another alternative that divert the flow (using pond diverter valve, i found there is 3/4" threaded that seems can be used for this application).
I am currently collecting the part and will try m00se suggestion, and if it does not work will try the alternative using a diverter valve.
I still like the alternative with diverter valve though as it will evenly divert the flow properly without adding a back pressure such on the left solution. Perhaps the check valve is unnecessary.
But as i have no experience using a diverter valve, perhaps something else might become as an issue that i fail to capture.
