Flow to carbon reactor and algae reactor

[gesock]

I have a 1 1/4" pipe feeding my manifold with 1/2" quick disconnect feeding my carbon reactor and algae reactor. Both items say to run at no more than 350 gph. How can I make sure that is what I've got going to them? I have a gate valve before the reactor (sorry can't send pics yet as I'm still putting it all together) and I was thinking of adding a flow meter to one line (assuming it would be the same flow for the unmetered line).

I'd rather not go through all that if someone out here has a better suggestion.

you can always put a measuring cup under the tee'd line, and capture a minute worth of water, and calculate the flow until it's right.
