Cerges' style reactor on a by-pass manifold.
This is my modification to a diy reactor design that has been out there for a little while now. I can "dial" in the flow rate through my reactor so the co2 is being dissolved correctly. My fx5 has a lot of flow for one of these reactors and would just push the bubbles through, not to mention the head pressure reduction on the filter output. So the by-pass is born (probably done many times by others). The idea is I can close off the ball valve some on the main line between the in and out lines from the reactor so enough back pressure is created to cause the water to flow through the reactor while still allowing flow through the main line. the ball valves on the reactor lines are always open all the way unless i want to take the reactor housing apart for maintenance.
I plumbed this all up this weekend and my bypass works like a charm. I haven't really played with the co2 yet to see how much I need to choke it back to get the proper flow rates yet. If I turn it all the way on to reactor I lose about 1/2 of my flow and I am worried about backpressure on my fx5. I am assuming I can get away with only maybe 1/4" turn on my manifold, so that 3/4 is just going straight through and maybe 100 gph through the reactor (creating an overall 1/8 to 1/4 reduction of flow from my fx5). I guess I will have to see how much flow it takes to dissolve 1-2 bps of co2. Has anyone here ever put an inline filter / heater / reactor on their fx5? should I be worried about motor life reduction or a leaky filter from backpressure?
