Two Little Fishies Kalkwasser 500g

Two Little Fishies Kalkwasser delivers a concentrated calcium hydroxide formula designed to support the skeletal growth of corals, clams, and coralline algae in established reef systems. Beyond calcium replenishment, this 500g mix works to stabilise alkalinity levels, maintain optimal pH balance, and reduce excess phosphates through natural precipitation. The enhanced protein skimming action helps keep your water column cleaner whilst building the foundation these organisms need to thrive. Ideal for serious hobbyists maintaining calcium-demanding reef environments.
