This chart is a salt water and reef aquarium lighting guide. It will help you determine the best aquarium light for your tank based on:
  • the dimensions & gallons of your tank (e.g. 75 Gallon 48" x 18" x 20" Tank)
  • the types of corals in the tank
 Different types of corals need different amounts of light:
  • Low Wattage: Reef tanks with soft corals and live rock
  • Medium Wattage: Reef tanks with soft corals, LPS corals and live rock
  • High Wattage: Reef tanks with soft corals, LPS & SPS corals and live rock
We highly recommend reading our Buying a Reef Light article. It will give you insight into why some lights are better than other lights.

NOTE: For those with existing canopies, you should look at the Chart For Choosing the Best Retrofit Lighting for a Reef Aquarium. We also have a Chart For Choosing the Best Lighting For Planted Tanks & Fish-Only Aquariums.
