Hey mate, your better off making a reactor! I'd say you have a large tank of your running a fx6 so the best way to get a good co2
spread is a spray bar and a reactor.
You have 2 choices with the reactor, either a "Griggs DIY reactor" or a "Cerges reactor" I personally feel the cerges is better.
Here's the links for how to make them:
Griggs - http://rotalabutterfly.com/rex-grigg/diy-reactor.htm
Cerges - https://glassboxgardeners.com/thread...2-reactor.346/
Just get the size hose barbs you require.
Both are very easy to make and all parts should be available at your local hardware store. Not very expensive to build either.
