Attached is what I plan to do, but not really sure if this is the best way or not.
After talking to several people at LFS and posting on boards this is what I came up with.
UV on it on pump in the sump, and returns to main return of the tank. I have 2 over flows that are on a T.
CO2 Reactor split from the return on the pump, and ball valve to control flow to CO2 Reactor.
Will this work? Will I get enough flow to the CO2 Reactor? I am told by manufacture that the CO2 Reactor could go direct off the pump, but I feel that a lot of risk to put everything to the CO2 Reactor. The CO2 Reactor has a pump or something in it that will disolve the CO2.
Should I put the Check valves in?
Any thoughts or changes I should make, as I plan to start this later today and in the morning.
