there are two problems with it. GFO
needs to be replaced every 4 weeks and Carbon needs to be replaced every 2 weeks. The second thing is the carbon is harder than the gfo
and can break it up and it get released into the tank. They really need different flows. The Gfo
needs to boil slightley and the carbon doesn't. the best thing to do is 2 seperate reactors that was you can replace the media at seperate times and save money.
