What method for reducing nitrates/phosphates do you use?

[Reef Pilot]

And if you browse through the first few pages of my journal, you can see some of my early struggles with nitrates before I finally figured it out. A couple years ago (also documented in my journal) I experimented with decommissioning my bio pellet reactor. That turned out to be a big mistake, as the nitrates returned with a vengeance and took many months to get them under control again.
