You can do both at the same time, but P04 is your bigger problem. I only tried carbon dosing for a very short time, and didn't like the work and attention involved. So have used only a bio pellet reactor for a long time. Keeps N03 at zero (or at least so low I can't measure any). And I go for a year+ without having to touch it. Once N03 is down to zero, pellet consumption slows down to almost nothing.
But with P04 that high, it will take some effort with Fozdown (carefully) to bring it down. Once it is down (all leached out of your sand and rocks), then it is easy to maintain with just GFO.
