{"product_id":"brightwell-aquatics-coral-amino-copy","title":"Brightwell Aquatics Lugol's Solution","description":"\u003cp\u003eBrightwell Aquatics Lugol's Solution is a highly concentrated iodine and iodide supplement for advanced reef aquarists, serving a dual purpose as both a regular iodine supplement and a coral dip for new arrivals. Iodine is a minor but essential element in natural seawater, and its role in a reef tank is often underestimated. It is used by corals, clams, and other zooxanthellate invertebrates to detoxify excess oxygen produced by their zooxanthellae, which in high concentrations can irritate sensitive tissue. Corals that shrink or close under intense lighting are often responding to this oxygen buildup, and maintaining adequate iodine levels allows them to remain open and thrive. Iodine also depletes quickly through protein skimming, activated carbon, and biological uptake, making regular supplementation important in well-filtered systems.\u003c\/p\u003e\n\u003cp\u003eThis is a product for experienced hobbyists only. The concentration is extremely high, and overdosing can cause serious harm to livestock.

Add to a high-flow area of the sump. Dose slowly and allow full circulation before retesting. Do not exceed the maximum dose listed on your label, and do not dose based on another bottle's concentration. Weekly dosing is recommended over daily dosing where possible to reduce the risk of accumulation. Reduce or skip dosing if running heavy activated carbon or aggressive skimming, as this will affect how quickly iodine is depleted.\u003c\/p\u003e\n\u003ch3\u003eStorage\u003c\/h3\u003e\n\u003cp\u003eStore in a cool, dry location away from direct sunlight.
