Kent Marine Concentrated Iodine Supplement

Provides bio-available iodine to reef inhabitants for better fish and algae growth, particularly benefits soft corals. Although present in salt mixes, iodine is rapidly used up in the system, and removed by protein skimming and ozone. Algae also use iodine. Concentrated Iodine Supplement replaces iodine needed for proper growth and health of invertebrates and algae. Contains a safe, stabilized form of iodine which will not destroy system bacteria. Recommended if you use protein skimmers, ozone, or have strong algae growth.
