"Coral Food gives (directly or indirectly) highly nutritional particles ranging in size from 5 - 150 micron and dissolved natural polymeric and monomeric nutrients. When dosed according to the instructions corals will have sufficient food to thrive without polluting the water. The organic load caused by this supplement is comparable to what is found in pristine seawater. This food is also ideal for sponges, tunicates, feather duster worms and many other organisms. Soft, leather and hard corals and many other organisms are highly capable in catching food particles.
But then the particle size must be within a certain range and it should signal the organisms that this is what they are waiting for. That is, it has the nutrients they require. All the nutrients obtained by the above described ways are used for growth and energy. This energy is used to carry out important biological processes resulting in well-being of the corals and other organisms"
