COLOMBO KH PLUS 250 ML(1250L)

The value should be 6-10DH KH. Test the water regularly and correctly, if the values ​​are low, use Colombo KH Plus. We recommend increasing the hardness by up to 2DH per day. Usage: 1 ml KH Plus per 5 liters of aquarium water increases the KH by 2 DH. So 10 ml is sufficient for 50 liters of aquarium water. If necessary, repeat the next day. KH Plus is suitable for tropical and cold aquariums. Keep out of reach of children.
