Additive S:

Doktorfisch Additive Sulfur was developed for the targeted increase of sulfur content (sulfate) in saltwater aquariums. Sulfur is required for the formation of skeletons and is involved in metabolic processes. A balanced sulfur level also promotes the activity of zooxanthellae, which significantly contribute to the energy supply and coloration of corals. The targeted addition of sulfur supports the ecological balance in the reef system and strengthens the vitality and color intensity of corals.
