JBL Aquaristik und Terraristik ProNovo BEL HOLIDAY

Feed your aquarium fish for up to 14 days with this food block. Simply place the block in the aquarium, where it will sink to the bottom and provide food for about 25 ornamental fish up to 10 cm in size for up to 14 days. The block is made from a calcium compound that adds some overall hardness to the water as it dissolves. It slowly dissolves through the fish's feeding, made from natural raw materials without artificial additives for a diet close to nature and healthy aquarium fish. Tested on JBL research expeditions in the tropics.
