Although present in salt mixes, iodide is rapidly used up by aquarium inhabitants and is aggressively removed through protein skimming, ozone, and filtration. It is important to supplement iodine regularly. Iodide supplement supplies a safe, stabilized form of iodide to reef inhabitants that will not harm biological filtration. 16 oz treats 4,700 gallons.
We recommend the use of a high-quality synthetic salt mix, accurate test kits, purified tap water (to minimize contaminants), and professionally-formulated supplements as the basis of a successful marine aquarium.
