So I have a manifold built in to my return line and haven't used it since I stopped running my phosguard reactor. I've read some articles about anemone tanks running carbon. I'm not entirely sure why it helps I usually don't run it. I have Kent carbon and was thinking of using it in my reactor since I now have 5 carpet anemones, 1 9" purple gig, 1 5" green gig, 1 14" red/pink haddoni and 3 mini maxis. I would like to hear some thoughts on this and what benefits or potential issues it has. Also, how do you run carbon in a reactor, no tumble?
