I try and run my tank as low maintenance as possible. I have nothing against running skimmers, GFO, carbon, calcium reactors, etc. I think they all have their place. For me, I would rather have the tank balanced naturally since it is more self-sustaining and doesn't require as much input on my end. I'm trying to stick to how Julian Sprung runs his tanks. No skimmer, etc. Just natural filtration and he has amazing results.
