Description
Iodion
Highly-concentrated, extended activity iodide solution.
Technical Background
Presence of iodine is vital to hermatypic invertebrates 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 likely attempting to shade their zooxanthellae symbionts to reduce
the rate of oxygen production. Iodide essentially bonds with oxygen to form
non-toxic iodate, relieving the need to shield zooxanthellae and enabling
the host organism to open more 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. The importance of iodine in a reef aquarium cannot be overstated. 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. All Brightwell Aquatics liquid
water care supplements are made with purified water and high purity materials.
Instructions and Guidelines
Basic: Shake product well before using. Add 5 ml (1 capful) of product per
50 US-gallons of aquarium water every two- to three-days or as needed to maintain
the iodine concentration within a range of 0.04 - 0.06 ppm. When used in this
fashion, 250 ml treats up to 2,500 US-gallons (9,464 L).
Advanced: Determine the total iodine concentration in the aquarium using
an accurate test kit before supplementing. Each ml of Iodion will increase
the concentration of iodine (“[I]”) in 1 US-gallon (3.785 L) of
water by 0.625 ppm. If the initial [I] in the aquarium is below 0.06 ppm,
add this product at the maximum rate of 5 ml per 25 US-gallons daily until
the desired concentration is attained, then dose daily or weekly as needed
(see below). Always try to maintain the [I] within a range of +/-0.02 ppm.
To determine the dosing rate of this product once the desired [I] has been
acquired, measure the daily rate of iodine uptake (i.e. the decrease in iodine)
in your aquarium by measuring the aquarium's [I] at the same time each day
over a one- to two-week period. To determine the daily dosing rate (preferable
to weekly dosing) for iodine maintenance: estimate the volume of water in
the entire aquarium system; divide the daily decrease in [I] by 0.625; multiply
this number by the volume of water in the system (in US-gallons) to get the
daily dosage required (ml) to maintain a stable [I]. Daily dosing maintains
a more stable [I] (and more natural environment) than dosing weekly, in which
the [I] spikes just after dosing and then gradually decreases throughout the
course of the week. Never overdose an iodine product, as severe overdosing
can harm livestock and the beneficial microbes that constitute the biological
filter.
Caution:
Keep out of reach of children. Not for human consumption. Contact poison control
center if ingested.
