I own a reactor, and if the day ever comes that I need to run GFO, carbon or some other product, I can. But the last time that happened was 15 years ago and I didn't know what I was doing.
Now I run a refugium with some macro algae, a filter sock I only replace when it is ready to start overflowing (once a week or so) and a properly sized skimmer.
