Provides necessary calcium to enhance the growth of hard corals, soft corals, and other reef invertebrates. Great for tube worms, snails, and clams, as well as purple, pink, and green encrusting calcareous algae (coralline algae). With regular use, corals open more often and stay attached to their skeletons better. Calcium is vital for the health and growth of corals and also plays a crucial role maintaining high pH needed in marine systems. Phosphate and nitrate free. Does not raise DOC levels. 16 oz treats 6,000 gallons. For best results, use Kent Kalkwasser Mix first.
Contains no EDTA, gluconates, lactates, or other sugars, which increase bioload and may accumlate over time and spur unwanted slime or bacterial growths and/or sequester trace elements.
Remember that establishing and maintaining proper water chemistry over the long term are the most important facets of marine aquarium husbandry. Accurate test kits are crucial to help you monitor and maintain water chemistry.
