Marc Weiss' Reef Vital DNA enhances growth pigmentation of coralline algae, anemones, sea mushrooms, sponges, tunicates, feather dusters, live rock and related organisms and interferes with the ability of Cryptocaryon (saltwater Ich) to adhere to fishes' skin. With regular use, live rock organisms proliferate with increased color. Adhesion to substrate is accelerated. Reduces nuisance algae and breaks down organic wastes, ammonia, nitrates, nitrites and phosphates. Promotes coral polyp regeneration and reproduction; aids damaged corals.
