Do you run gfo and carbon together?

Curious what people do; along with what reactor they use if any.

I do a 50/50 mix in a nextreef mr1 reactor

I use them as-needed (together or not) in the mesh post-filter of my skimmer:

I run GFO in a reactor and place a bag of carbon in a high flow area in my sump when needed.

Just to add to this. I am really careful to not strip the tank since I did that before and it caused problems. So I use 1/3 of what is recommended by BRS. It only really lasts a couple of weeks before it is depleted, but the tank wont strip that way.

I used to. I was running biopellets and gfo / carbon mixed together. I was dropping my phosphates too low and now just run a small amount of pellets and carbon for water clarity.
