Yep, dual canister from BRS. Mix of GFO and small particle carbon in the first canister and ROX carbon in the second. Slow flow but it makes a difference. Never have used the second outlet off the manifold.On your manifold are you running your GFO/ Carbon reactor off it? I have thought about this, but wasn't sure I would have enough flow for this, I have a Jebao DC 9000 that's controllable, and another concern was me only planning to run a single return on a 75g display....
what are your thoughts? should I add a ball valve and reduce it to use for my reactor?
(not trying to thread jack here, just saw an opportunity to ask a question )
