Sera kH/pH-Plus

The carbonate hardness KH is one of the most important water parameters in an aquarium A majority of the fish species kept in freshwater aquariums refers relatively hard water Furthermore the KH serves as a buffer that prevents dangerous pH value variations among others rapidly sinking pH value The KH should be kept at least at 6 dKH for all community tanks as a basic rule considerably higher for special cases such as African cichlids This ensures the fish do well and the aquarium water turns out particularly durable and easy to maintain sera KH pH plus precisely and lastingly raises the KH to the desired value The pH value is gently raised as well and above all safely stabilized Recommended dosage 5 ml sera KH pH plus increase the carbonate hardness in 30 l of water by 1 dKH We recommend raising the KH in an aquarium by not more than 2 dKH per day Check the pH and KH values with the sera pH Test and the sera kH Test 30 minutes before and after the addition
