(Pass Me the Vodka)

Over time your system will start to accumulate phosphates and nitrates. There are pretty much three accepted methods folks use to remove them.

  • Water Changes (20% or more) as often as you can.
  • Bio Pellet Reactor and/or Granulated Ferrous Oxide (GFO) Reactor
  • Refugium full of Marine Plants to consume the phosphates and nitrates.

The acceptable levels for these substances are Nitrates at 4 ppm and Phosphates at 0.03-0.06 ppm. Less than these amounts and some of your corals will fail as they this for food.
