Features
- Calcium supplement for saltwater aquariums
- 500ml (17 oz)
Description
Calcion
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 29 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 29; 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.
Caution: Keep out of reach of children. Not for human consumption.
