Labpak Kalkwasser Calcium Hydroxide 500g

Calcium Hydroxide is the proven standard for maintaining calcium concentration and alkalinity in closed marine aquaria. The calcium provided is directly used by calcifying organisms, and the hydroxide ions provided readily convert dissolved CO2 into bicarbonate and carbonate ions, which are also directly used by calcifying organisms. The net result is no ionic imbalances in the aquarium water, which can occur through the prolonged use of other calcium supplements, such as calcium chloride.

Calcium Hydroxide (Kalkwasser) is a excellent way to keep your calcium levels topped up with a kalkwasser mixer, 500g will be packaged in a bag much cheaper than Rowakalk and just as good.

m with excellent results on maintaining or raising calcium levels.
