Brightwell Aquatics Lugol's Solution 30mL
Lugol's Solution for Use by Advanced Reef Aquarium Hobbyists.
Overview:
Brightwell
Aquatics Lugol's is an extremely powerful iodine/iodide solution. It
should only be used by advanced aquarists. Lugol's is not formulated for
human use.
Technical Background:
Brightwell
Aquatics Lugol’s is an extremely powerful iodine solution. It should
only be used by advanced reef aquarists to dose iodine as well as to
create a dip for corals and their allies.
The
importance of iodine in a reef aquarium cannot be overstated. Presence
of iodine is vital to hermatypic invertebrates (i.e., corals, clams, and
their allies that harbor zooxanthellae) because it is used to detoxify
excess oxygen produced by zooxanthellae. This oxygen irritates sensitive
tissue. Corals and clams that appear to shrivel or close under intense
lighting are attempting to shade their zooxanthellae crop to reduce the
rate of oxygen production. Iodine (as the iodide ion) essentially bonds
with oxygen to form non-toxic iodate, relieving the need to shield
zooxanthellae and enabling the host organism to open fully.
The
predominant form of iodine in seawater is iodide. The natural seawater
concentration of all iodine species combined is approximately 0.06 ppm,
classifying it as a minor element. Even in this small concentration,
iodine is required for survival of fishes, crustaceans, macroalgae and
kelp, and hermatypic invertebrates alike. Iodine binds rapidly with
latent organic material and is passively removed by aggressive protein
skimming and the use of organic-adsorption products such as activated
carbon and specialty resins. The combined biological and chemical
depletion of iodine necessitate that its concentration be monitored and
the aquarium supplemented as needed. The rate at which iodine is
extracted from the water is determined by the stocking density of
reef-building livestock, type of lighting, and other biological,
physical, and chemical conditions. Once the rate of iodine uptake in the
aquarium has been determined, the proper dosing rate of this product
can be easily calculated.
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].
