Brightwell Lugol's Iodine Solution

Overview

Brightwell Lugol's is an extremely powerful iodine/iodide solution.  It should only be used by advanced aquarists.

Instructions and Guidelines

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].

Caution:

Keep out of reach of children. Not for human consumption. Contact poison control center if ingested.
