Brightwell Aquatics Kalk+2 is an advanced powdered Kalkwasser supplement that provides calcium, magnesium, and strontium in the same ionic ratios found in natural aragonite. Designed for reef-building invertebrates such as corals, clams, and calcareous algae, it helps maintain pH and temporary alkalinity while avoiding the addition of conservative elements like chloride. Formulated by a marine scientist, Kalk+2 improves upon traditional powdered calcium supplements and is ideal for experienced hobbyists using controlled dosing methods.
