Brightwell Aquatics Lugol's Solution 30ml
Instructions and Guidelines for use in the aquarium
Note: Lugol's has been manufactured in two strengths and was changed recently due to government regulations. The strength you have may be different than that below. Your label will reflect the strength you have. 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 12 ppm, or approximately 0.6 ppm per drop. EZ Calculations for use in the aquarium: Multiply tank capacity in gallons x ppm increase desired x .07570 = ml of product to add. Example to raise the concentration of iodine in a 100 gallon aquarium by .02 ppm, the calculation is: 100 x .02 x .07570 = 0.15 ml. To get the number of drops required, multiply this number by 20, so this would be 0.15 ml * 20 = 3 drops. (a dropperful is 1 ml or 20 drops).
Instructions and Guidelines for use as a dip for new corals
Note: Lugol's has been manufactured in two strengths and was changed recently due to government regulations. The strength you have may be different than that below. Your label will reflect the strength you have. Read your bottle to determine the strength you have. The label on the outer package will give you the ppm that your product will raise a gallon of water. Draw one gallon of aquarium water from your aquarium and use the following calculation to determine how much Lugol's to add.
EZ Calculations for a Dip: 14.4 divided by the ppm per gallon on the label = ml to add to one gallon of tank water in your bucket. If your label says the Lugol's will raise 1 US gallon of water by 12 ppm, the calculation would be: 14.4 / 12 = 1.2 ml of Lugol's. So you would add 1.2 ml or a dropperful and then 20% of another dropperful to 1 gallon of tankwater that you placed in the bucket. That would also be 1 dropperful plus 4 drops. (a dropperful is 1 ml or 20 drops). Corals may be soaked for 10 to 12 minutes. SET A TIMER!
Caution: Keep out of reach of children. Not for human consumption. Contact poison control center if ingested.
