Dawn Sci’s Aquatic Iodine Supplement provides bio-available iodine to reef inhabitants. Although present in salt mixes, iodine is rapidly used up in the system, and removed through protein skimming, ozone and filtration. Aquatic Iodine Supplement supplies iodine needed for proper growth and health of invertebrates and algae. It contains a safe, stabilized form of iodine which will not destroy system bacteria, as some competing products will. It contains no organic forms of iodine which can pollute the system.
Directions: Add 1 teaspoon (1 capful or 5 ml) per 50 gallons (190 l) every week or 8 drops each day.
