- Kalk+2 is an advanced Kalkwasser powdered supplement enhanced to include not only the traditional calcium hydroxide, but strontium hydroxide and magnesium hydroxide also.
- 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.
