Kalkwasser
Developed by Peter Wilkens to replenish calcium and maintain alkalinity in any reef aquarium. Promotes a cleaner and healthier aquarium, helps impede growth of hair algae, and encourages coral and calcareous algae growth. It also reacts with fatty acids and other organic compounds. Plus a naturally boosted pH enhances protein skimming. A one pound canister makes up to 220 gallons of solution.
