Dennerle Black Cones are natural alder cones that are used for water and fish care in freshwater aquariums.
With the Black Cones, you can care for and protect your aquarium fish in a natural way with valuable humic and tannins. With the Black Cones, you can achieve natural and tropical-like aquarium water and also promote the well-being, vitality and readiness of your animals to spawn. The ingredients protect and strengthen the mucous membrane and gills of the fish and strengthen the shells and gills of shrimps and crustaceans. They also strengthen the body's defences, inhibit harmful germs and reduce stress. With Black Cones, you can prevent fungal diseases in your fish, but also in the spawning of fish eggs. In a natural and foolproof way, you can increase the breeding success of your animals!
Black cones mildly acidify the aquarium water and stabilise the pH. This makes them ideal for new installations and particularly recommended for fish from black water areas such as discus fish, neons, scalars, dwarf cichlids and antenna catfish.
Application: Add 4-6 cones to 100 litres of aquarium water every 2-3 weeks. After 2-3 weeks, replace the alder cones or leave them in the aquarium as decoration. If you should use Catappa products at the same time, you must adjust the dosage accordingly.
Our expert Oliver Knott recommends:
Black cones are the absolute non-plus-ultra in aquaristics and especially in breeding!
