Maintain a stable and healthy aquarium environment with ARKA Carbonate Hardness Powder. This specially formulated product is designed to quickly and safely raise carbonate hardness (KH) in both freshwater and marine aquariums. Ensuring optimal nitrification and supporting healthy coral growth, this powder is essential for any serious aquarist.
ARKA KH Booster provides bacteria fuel which is vital for the nitrification process, where dangerous ammonium/ammonia is broken down. A sufficient KH value of at least 3 dH° in freshwater and 8 dH° in marine water is crucial for this process. The fast-acting, fully dissolvable powder is ideal for use with RO water, soft tap water, or rainwater tanks, and is suitable for a variety of aquarium types, including planted, shrimp, and reef aquariums.
