The Kalkwasser Premium Acquafauna 500g<\/strong> is a high-purity calcium hydroxide supplement,<\/strong> developed to replenish calcium and alkalinity (KH) in marine aquariums<\/strong>, especially reef systems with hard corals (SPS and LPS), soft corals, and other calcifying organisms.<\/p>\n

Its formula provides a high concentration of bioavailable calcium, essential for the healthy growth, development, and calcification of corals, coralline algae, tridacnid clams, and other marine invertebrates. In addition, it helps maintain a high and stable pH, supporting the chemical balance of the aquarium water. <\/p>\n

Another important benefit of Kalkwasser Acquafauna is its ability to precipitate phosphates, reducing unwanted nutrients that promote algae growth. It also reacts with organic compounds, enhancing the efficiency of the protein skimmer and contributing to cleaner, crystal-clear water.<\/p>\n

Benefits of Kalkwasser Premium Acquafauna<\/h3>\n
    \n
  • High concentration of high-purity calcium.<\/li>\n
  • Efficient replenishment of calcium (Ca) and alkalinity (KH).<\/li>\n
  • Supports calcification and the growth of corals and other calcifying organisms.<\/li>\n
  • Helps maintain stable pH levels in marine aquariums.<\/li>\n
  • Contributes to phosphate precipitation.<\/li>\n
  • Improves protein skimmer efficiency.<\/li>\n
  • Ideal for marine reef aquariums with high calcium demand.<\/li>\n<\/ul>\n

    Why use Kalkwasser in a marine aquarium?<\/h3>\n

    During the calcification process, corals and other marine organisms continuously consume calcium (Ca\u00b2\u207a) and carbonates, naturally reducing calcium, alkalinity (KH), and pH levels in the aquarium. Replenishing these elements is essential to maintain healthy coral growth and stable water parameters. <\/p>\n

    Regular use of Kalkwasser Premium Acquafauna helps maintain the recommended parameters for reef aquariums:<\/p>\n

      \n
    • Calcium (Ca\u00b2\u207a): between 380 and 420 mg\/L<\/li>\n
    • Alkalinity (KH): between 7 and 10 dKH (125 to 179 mg\/L)<\/li>\n<\/ul>\n
