Carbon/GFO reactors - use them?

[calreef18]

I use to use both but now only carbon sparingly. I had a problem with nutrients early on in my system, but the GFO helped bring it down. System is much healthier without all the extra GFO and carbon, just seemed to strip out too many things. Tank has stabilized enough now also to have low nutrients even without GFO.

I have two single Two Little Fishies reactors that I turned into a dual reactor. GFO in first Reactor then Carbon in the second. Helps if any of the GFO runs out the reactor it will get trapped in the carbon reactor. I run them both on a Maxi jet 1200.
