Plumbing for UV, CO2 Return.

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.

Thanks

i would run both co2 and uv off same pump
or separate return lines if you use two pumps
i think returning two pumps to one line will be to unpredictable

I thought of doing that, but the pump I have for the UV is small, it only maxi jet 900. As for the returns, I think I want the main pump to return to both returns, I would really have to drop the flow of the main pump as it a MAG18.

i would be concerned the big pump would way over power the pressure generated from the small one , it could reduce the small pump to a trickly or worse start flowing backwards
you could forget the small pump and simply split the large pump to feed both reactor and uv
then run two out let lines to tank

On my 180, I have the mag 18 as my return pump and use the fractioning impeller to mist the CO2. My UV runs off another pump and draws and returns to the sump.

yes i think that is a way easier and less likely to have flow issues

Thank you for the advise. I think this is the best way as well. Plus with having the unions & ball valves on the reactor I can lower water flow if needed and also pull it out of the loop when I want to do maint on it.

Do you think I need to put check valve anywhere? I have 2 industrial ones.

your returns to tank run over top of tank and the outlets to sump are over flows right?
so if pump turns off it will only drain tank to inlet and/or outlet level
are the check valves flap type or spring
the spring type add lots of resistance , have high cracking pressure
