Stop Chasing Numbers!

by Ben Barber

Don’t chase a specific number, chase stability. Corals thrive on stability not a specific value of any one specific number. If you are in the right ranges and stable your corals will be happier and healthier than any one specific set of numbers will make them. Not to mention you won’t drive yourself crazy trying to achieve “perfection” on your numbers. Below are some ranges that our corals have found the most success in over the years.

  • Alkalinity – 7-11 dKh
  • Calcium – 380-450
  • Magnesium – 1250-1500 (1400+ if you keep goniopora)
  • Nitrates – above 0, less than number depends on your corals 20 or less is good rule of thumb.
  • Phosphates above 0, less than number depends on your corals .1 or less is good rule of thumb.
  • Salinity – 1.024-1.027
