CONES – Natural Alder Cones for Aquarium Use, 40-Piece Pack
CONES Alder Cones are a natural and hand-harvested solution for maintaining healthy water conditions in tropical freshwater aquariums. With 30% more tannin content, they are more effective than ever in supporting fish health and biological balance within your tank.
These cones are ideal for betta, discus, dwarf cichlids, tetras, and bottom-dwellers, providing antifungal protection, mucous membrane support, and immune system reinforcement. The tannins released help mimic blackwater habitats, slightly lowering pH and creating a calming environment that reduces stress for sensitive fish.
Each cone slowly releases its beneficial substances over approximately three weeks. After this period, you can replace the cones or leave them in the tank as natural decoration, enhancing aesthetics while providing hiding spots and shadowed areas.
How to use:
Add 4–6 cones per 100 litres of freshwater
Place cones directly into the tank
After 3 weeks, replace or keep as decoration
