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 soln 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.
