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.

Kalk+2
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.
Caution: Calcium hydroxide is a caustic
material; if inhaled, remove to fresh air, and in case of
contact flush skin and/or eyes with fresh water for 15 minutes.
Drink 16-oz. fruit juice if swallowed and seek immediate medical
attention. Keep out of reach of children. Not for human
consumption.
