Brightwell Aquatics Kalk+2 - 1.8kg | Advanced Kalkwasser Supplement

Brightwell Aquatics Kalk+2 is an advanced kalkwasser-based powdered supplement formulated for experienced marine and reef aquarists who require precise control of mineral balance and pH. Enhanced beyond traditional kalkwasser, Kalk+2 includes calcium, magnesium, and strontium hydroxides—supplied in the same ionic ratios found in aragonite, the skeletal material produced by corals, clams, tube worms, and calcareous algae.

This refined formulation supports robust skeletal growth, provides temporary alkalinity, and helps maintain pH within the desired range when dosed correctly. Kalk+2 adds no conservative elements such as chloride, helping preserve long-term ionic balance in reef systems. Developed by a marine scientist, it represents a modern improvement on classic kalkwasser supplementation trusted by seasoned reef keepers for decades.
