Product details

Effectively increases the carbonate hardness and stabilises the pH value in the salt water aquarium. Promotes the growth of all organisms that require calcium carbonate, such as stone corals, fan worms, mussels and various coralline red algae. Suitable for dosing pumps. Contains 5,000° dKH 1,000 mg K. The main elements hydrogen carbonates (HCO3), calcium (Ca) and magnesium (Mg) have a decisive impact on the water stability (ph-value, alkalinity / carbon hardness) in the reef aquarium. In the marine water aquarium the carbon hardness / alkalinity should be between CH 7 and CH 9 °dH and is decisive for the buffering capacity in marine water. KH+ liquid reliably increases the carbon hardness and buffers the pH value in the marine water aquarium. Carbonates are constantly consumed by lime-absorbing organisms such as hard corals, mussels, lime tube worms, various coralline red algae as well as through biogenic decalcification. High pH oscillations and an under-supply of all calcifying organisms are prevented by regular addition.

Dosage: 20 ml increase the carbonate hardness / alkalinity by 1 °dKH / for every 100 l.

The alkalinity or carbonate hardness (KH) is a measure of the buffer capacity of the water and is decisive for a stable pH value in the aquarium. The alkalinity or KH should be between KH 6 and KH 8°dH in a marine aquarium. In natural seawater, the alkalinity is approx. 7.0°dH. This value is stable in the sea due to the large water mass, but in the aquarium biochemical processes can have a great influence on the carbonate hardness and change it. Stony corals, mussels, soft corals and calcareous algae extract calcium and carbonate ions from the water during calcification and store calcium in the form of calcium carbonate. This reduces the Ca and KH values. Regular addition of Power KH+ or KH+ liquid stabilises the alkalinity and prevents the dangerous drop in acidity. Due to the different number of consumers, each aquarium has its own needs. In some cases, a well growing aquarium can ''consume'' 1 KH per day. Therefore, the KH value must be checked at least once a week.

Background Carbonate hardness or alkalinity?

Carbonate hardness is an outdated term from drinking water analysis and is defined as part of the earth's alkali metals that can be precipitated by heating to form carbonates (scale). This is also where the term ''temporary hardness'' comes from. Due to the different composition of seawater and drinking water, however, there is neither temporary hardness nor carbonate hardness in seawater analysis, but only the term alkalinity. Alkalinity is therefore equivalent to the simplified notation KH.
