Features
- 400g / 14.1 oz
- High-purity powdered calcium.
- 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.
- Stronger and more economical than liquid calcium solutions; created for
hobbyists maintaining multiple reef aquaria.
- Formulated by a marine scientist.
Description
Calcion P
It is recommended that the calcium concentration in the aquarium
be determined by using an accurate test kit prior to supplementing. Do not
add this product directly to an aquarium containing live animals without first
diluting in water as directed.
Technical Background
Calcium 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 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.
Instructions and Guidelines
Basic : Dissolve 2 grams (~½ teaspoon) of product per 20 US-gallons
of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed
to maintain the calcium concentration within a range of 412 - 450 ppm. When
used in this fashion, 800 g treats up to 8,000 US-gallons (30,283 L).
Advanced: Create a stock solution by dissolving 10 grams (~5 teaspoons) of
Calcion-P in 8-fl. oz. of fresh water (preferably purified); each ml of the
solution will increase the calcium concentration (”[Ca2+]”) in
1 US-gallon (3.785 L) of water by 2.50 ppm. [Reference: Each g of Calcion-P
will increase the [Ca2+] in 1 US-gallon (3.785 L) of water by 95 ppm.] If
initial [Ca2+] in the aquarium is below 412 ppm, add stock sol’n at
maximum rate of 10 ml per 20 US-gallons daily until desired concentration
is attained, then dose daily or weekly as needed (see below). Maintain [Ca2+]
within a range of +/-10 ppm. Once desired [Ca2+] has been acquired, measure
aquarium's [Ca2+] at the same time each day over a one- to two-week period
to determine the daily rate of calcium uptake (i.e. the decrease in calcium).
To determine daily dosing rate (preferable to weekly dosing): estimate volume
of water in entire aquarium system (US-gal.); divide the daily decrease in
[Ca2+] by 2.50; multiply this number by volume of water in system to obtain
daily ml of stock sol’n required to maintain stable [Ca2+].
Caution: Keep out of reach of children. Not for human consumption.
