Brightwell Calcion-P Dry Calcium Supplement 400 Gm
Brightwell Calcion-P Calcium Supplement 400 GM
200 g, 400 g, 800 g, 3.2 kg, 16 kg Overview â€˘ High-purity powdered
â€˘ 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.
â€˘ Stronger and more economical than liquid calcium solutions; created
for hobbyists maintaining multiple reef aquaria.
â€˘ Formulated by a marine scientist.
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.
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
Basic : Dissolve 2 grams (~Â˝ 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 (â€ť[Ca2+]â€ť) 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 solâ€™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 solâ€™n required to maintain
Caution: Keep out of reach of children. Not for human consumption.
