The Sera Kh/Ph-Plus regulates and stabilizes the pH value.

• It is effective against biological calcification.
• Creates suitable conditions (e.g. for African cichlids).
• Carbonate hardness (KH) is one of the most important water parameters in the aquarium. Many fish species prefer slightly hard water.
• In addition, KH acts as a buffer that prevents dangerous fluctuations in pH value (including sudden drops in pH value).
• KH should be maintained at least at 6°dKH in all community aquariums as a basic rule (and higher in special cases such as aquariums with African cichlids).
• This ensures the well-being of the fish, while stabilizing the aquarium water and making maintenance easier.
• Sera KH/pH-plus increases the KH value accurately and for a longer period of time to the desired level.
• The pH value also increases slightly and, above all, is safely stabilized.
