Kalk+2

• 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.
• Available in 100g, 225g, 450g, 1.8kg, and 9kg sizes.

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. 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.
