Calcium, Magnesium, and Strontium Supplement for all Reef and Marine Aquaria.Overview:- Contains calcium, strontium, and magnesium in the same ionic ratios found in aragonite.
- This
unique feature increases the usefulness of Kalk+2 to reef-building
invertebrates such as corals, clams, calcareous algae, etc.
- Provides temporary alkalinity and helps maintain pH within the desired range when used as directed.
- Adds no conservative elements, such as chloride, to the aquarium.
- Improves upon the industry-standard powdered calcium supplement over the past three decades.
- Formulated by a marine scientist.
Technical Background:Calcium,
magnesium, and strontium are required for the formation of aragonite,
the skeletal material of reef-building invertebrates such as corals,
clams, tube worms, and their respective allies. Brightwell Aquatics
Kalk+2 provides these elements and may also be used to help regulate pH
in reef aquaria. Kalk+2 does not contain chloride salts, which is a
strong point for some hobbyists. The use of kalkwasser-type products
remains very popular with many seasoned hobbyists, regardless of
innovations in calcium-delivery methods.
Instructions and Guidelines:Kalk+2
is intended for use by experienced hobbyists who are familiar with
kalkwasser (calcium hydroxide-based) products. The calcium concentration
(”[Ca2+]”) and pH in the aquarium should be determined by using an
accurate test kit prior to supplementing. Do not add this product
directly to an aquarium without diluting in water as directed, and do
not overdose; it must be added in a controlled fashion with a dosing
device. Create a stock solution by dissolving 6 grams (~1 tsp) of Kalk+2
in 1 US-gallon of fresh water (preferably purified) and allowing at
least one hour for any settling to occur; each ml of the saturated sol’n
will increase the [Ca2+] in 1 US-gallon (3.785 L) of water by 2.3 ppm,
strontium concentration by 0.04 ppm, and magnesium concentration by 0.06
ppm. This solution must then be dosed/dripped into the aquarium at such
a rate that salinity does not fall below 1.021 g/cm3 and pH does not
increase by more than 0.1 every hour, nor is it ever allowed to exceed a
value of 8.5. Dosing at night when pH in a reef aquarium is naturally
depressed is often performed to avoid exceeding the maximum allowable pH
value. If the [Ca2+] in an aquarium is gradually dropping despite using
this product as directed, the rate of evaporation may be insufficient
or pH may be too high to dose sufficient calcium to compensate for the
rate of removal by reef-building aquarium inhabitants and/or undesirable
chemical reactions. In this case, a secondary calcium supplement may be
needed to occasionally re-establish the natural seawater concentration
of calcium in the aquarium.
