Concentrated Calcium Supplement for All Marine Fish & Reef Aquaria.Overview:- Highly-concentrated ionic calcium solution.
- Increases the concentration of calcium in marine aquarium water to provide corals and other reef-building invertebrates with one of the most important elements required for growth.
- Is ionic rather than chelated, and contains no unwanted organic material such as EDTA, gluconate, or polygluconate.
- Over 50% stronger than most competing products.
- Free of phosphate, silicate, and organic material.
- Formulated by a marine scientist.
Technical Background:Calcium
is one of the most prevalent ions in seawater, and is required for the
formation of aragonite, the skeletal material of reef-building
invertebrates such as corals, clams, tube worms, and their respective
allies. In seawater, calcium is present at a concentration of
approximately 412 ppm; in reef aquaria, maintaining calcium within a
range of 412 - 450 ppm will enable corals and other reef-building
invertebrates to grow rapidly when all other physical and chemical
requirements are met. [Magnesium, strontium, and carbonate ions are also
complexed into aragonite, and their importance in a reef aquarium
cannot be overstated.] The rate at which calcium 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; therefore, each aquarium will have different requirements
for the rate of calcium supplementation. Once the rate of calcium uptake
in the aquarium has been determined (see opposite), the proper dosing
rate of this product can be easily calculated. It is recommended that a
quality salt mix with the proper (not augmented) alkalinity and
concentrations of major, minor, and trace elements be used to establish
natural seawater parameters in the reef aquarium, providing a stable
ionic foundation on which to build.
All
Brightwell Aquatics liquid water care supplements are made with
purified water and high purity materials. We develop formulae for
aquaria based on empirical data, using observation and measurement
rather than theory.
Instructions and Guidelines:Basic:Shake
product well before using. Add 5 ml (1 capful) of product per 50
US-gallons of aquarium water every other day or as needed to maintain
the calcium concentration within a range of 412 - 450 ppm. When used in
this fashion, 250 ml treats up to 2,500 US-gallons (9,464 L).
Advanced:Determine
the calcium concentration in the aquarium using an accurate test kit
before supplementing. Shake this product well before each use. Each ml
of Calcion will increase the concentration of calcium (“[Ca2+]”) in 1
US-gallon (3.785 L) of water by approximately 40 ppm. If the initial
[Ca2+] in the aquarium is below 412 ppm, add this product at the maximum
rate of 10 ml per 20 US-gallons daily until the desired calcium
concentration is attained, then dose daily or weekly as needed (see
below). Always try to maintain the [Ca2+] within a range of +/-10 ppm.
To determine the dosing rate of this product once the desired [Ca2+] has
been acquired, measure the daily rate of calcium uptake (i.e. the
decrease in calcium) in your aquarium by measuring the [Ca2+] at the
same time each day over a one- to two-week period. To determine the
daily dosing rate (preferable to weekly dosing) for calcium maintenance:
estimate the volume of water in the entire aquarium system; divide the
daily decrease in [Ca2+] by 40; multiply this number by the volume of
water in the system to get the daily dosage required (ml) to maintain a
stable [Ca2+]. Daily dosing maintains a more stable [Ca2+] (and more
natural environment) than dosing weekly, in which the [Ca2+] spikes just
after dosing and then gradually decreases throughout the course of the
week.
