Brightwell Lugol’s Solution | Advanced Iodine & Iodide Concentrate

Brightwell Lugol’s Solution | Advanced Iodine & Iodide Concentrate

Brightwell Lugol’s Solution is an extremely powerful iodine and iodide supplement designed specifically for the advanced reef aquarist. Iodine is a critical minor element in natural seawater, and its role in a closed reef system is vital for the health of fish, crustaceans, macroalgae, and hermatypic (reef-building) invertebrates.

Iodine is particularly famous for its ability to help corals manage oxidative stress. When corals are under intense lighting, their symbiotic algae (zooxanthellae) produce oxygen that can irritate sensitive coral tissue. Iodine bonds with this excess oxygen, neutralizing it and allowing corals and clams to remain fully expanded under high-par lighting.

Key Benefits:

• Tissue Protection: Helps corals and clams detoxify excess oxygen, preventing them from shriveling under intense light.

• Molting Support: Essential for the healthy molting of shrimp, crabs, and other crustaceans.

• Pigment Enhancement: Supports the natural coloration and vitality of soft and stony corals.

• Emergency Dip: Can be used to create a professional-grade coral dip for cleaning new arrivals or treating damaged specimens.

• High Purity: Formulated with Potassium Iodide and Iodine in a purified water base.

Dosing Instructions & Guidelines

⚠️ Warning: Lugol’s is highly concentrated. Overdosing can be toxic. Always test your iodine levels before and during supplementation.

1. Determine the iodine concentration in the aquarium using an accurate test kit before supplementing. Each ml of Brightwell Aquatics Lugol’s will increase the concentration of iodine (“[I]”) in 1 US-gallon (3.785 L) of water by 34 ppm, or approximately 1.7 ppm per drop. Add this product at the maximum dosage of 1 drop (1/20th ml) per 35 US-gallons daily to maintain a concentration of 0.05 ppm. Always try to maintain the [I] within a range of +/-0.02 ppm. Determine the required daily dosing rate (recommended to weekly dosing) by measuring the aquarium's [I] at the same time each day over a one- to two-week period. Estimate the volume of water in the entire aquarium system; divide the daily decrease in [I] by 1.7; multiply this number by the volume of water in the system to get the daily dosage required (drops) to maintain a stable [I].

Technical Background: Depletion Factors

Iodine is rapidly depleted in the modern reef aquarium. It binds quickly with latent organic material and is passively removed by:

• Aggressive Protein Skimming

• Activated Carbon

• Organic Adsorption Resins

• Biological Uptake by rapidly growing corals and macroalgae.

Regular monitoring and small, consistent dosing are superior to large, infrequent additions to ensure a stable environment.
