Targeted KH increase – ARKA KH-Booster quickly raises carbonate hardness in any fresh or saltwater aquarium with a special mix of elements, and helps to buffer pH swings in the aquarium water. Nitrification and coral growth – Bacteria only break down ammonium and ammonia with sufficient carbonate hardness: at least 3 dH° in freshwater and 6 dH° in saltwater. The Booster also supports coral growth. 500 g for regular use – The medium size suits medium tanks and ongoing water-value care, even with soft water and reverse-osmosis water, in aquascaping, cichlid and saltwater aquariums. Easy to dose – One level measuring spoon (6 g) per 100 litres raises the KH value by 2.5 dH°. Optimal is 6–10 dH° in saltwater and depends on the stock in freshwater. Check water values regularly. For all aquarium animals – Suited to ornamental fish, corals, plants and invertebrates, and combinable with ARKA pH products. The high-purity, soluble powder does not cloud. Keep away from children, do not inhale.
