$13.99Price

Extremely powerful & concentrated iodine/iodide solution.  

  • Overview

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

  • Instructions & 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].
