Shrimp, lobsters, and crabs have an outer skeleton made of a combination of chitin and calcium carbonate. These crustaceans grow by shedding their old exoskeleton and producing a new one (molting). When they are young, they molt frequently until they reach adulthood, after which molting continues but at a slower rate. Adding iodine to closed aquatic systems that house crustaceans has consistently been shown to stimulate molting in specimens that haven't molted before.

Florin-I is a supplement that provides iodine and iodide to crustaceans. The iodine is released slowly over time, while the iodide is available as a free ion. To achieve the best results, it is important to feed the crustaceans appropriate foods and maintain the water chemistry within the recommended ranges. Florin Delta GH+, Florin Delta KH+, NeoTiger KH+/GH+, or Caridina GH+ supplements can help maintain the proper levels of total dissolved solids (TDS), general hardness, alkalinity, and elements that enhance the coloration and food utilization of crustaceans. FlorinMulti can also be used to provide additional essential elements for their well-being.
