Broadcast or Target feeding

Coral foods are often designed for a specific type of feeding. To achieve the best results for your aquarium, you should understand what each method means.

Broadcast feeding is when you disperse the food evenly to the tank to feed everything in the tank. It is less controlled so you need to make sure that you are using the right amount of food. Target feeding on the other hand usually uses a syringe to feed the food directly to the coral.

Liquid and Pellet Food

You must make sure that you are using the correct type of food on your tank and that it properly caters to the needs of your aquarium. Pellets work best for target feeding a coral colony but because of its size, it is mostly limited to corals with larger mouths.

Most corals depend largely on phytoplankton for their nutrition. These are microscopic marine algae.
