pH / KH Fit plus: Optimises the carbonate hardness and the pH value

To increase the carbonate hardness and pH value. Prevents dangerous pH value oscillations. Acts immediately without clouding. For fresh and marine water.

Dosing:

20 ml for every 100 l aquarium water increase the carbonate hardness by one °KH

The carbonate hardness is one of the most important water values in the aquarium. While the pH value is well known to most fishkeepers, many are not aware of the significance carbonate hardness has. The carbonate hardness stabilises the pH value[1] and prevents the dangerous sudden drop in acidity. Unfortunately, the carbonate hardness in the aquarium suffers from chronic ‘consumption’ because various biological and chemical processes constantly attack the carbon hardness.

Two mechanisms are of particular significance in this respect:

On the one hand, the carbon hardness is constantly consumed by the biological decomposition of protein compounds from the fish food because the decomposition of proteins produces an acid. The carbon hardness neutralises this acid (it is this process that makes the carbon hardness so valuable) during which the carbon hardness is gradually consumed.

The other process that uses up carbon hardness is called biogenic decalcification: During daytime, with intensive plant growth (or algae growth), a lot of CO2 is consumed. An excessive increase in the pH value (over 9) is prevented by carbonate hardness and general hardness as insoluble lime is formed from them. This process consumes both carbonate and general hardness.

If there is no more carbonate hardness, catastrophe follows. Even the smallest amount of acid, created by feeding the fish for instance, will cause the pH value to nosedive. This is referred to as a sudden drop in acidity – with fish dying as a possible consequence.

pH / KH Fit is a buffer for the pH value and thus the safety belt for your fish stock. Protect your fish by regularly checking your carbonate hardness and adjusting the value to between 4 and 8 °KH. With lower values there is a risk of the carbonate hardness disappearing altogether, and the associated, dramatic consequences become possible. Significantly higher values on the other hand can have a negative effect on some fish and plants.
