Dupla Alder Cones

Dupla Alder Cones

Naturally harvested from untouched black alder trees (Alnus glutinosa), Dupla Hobby Alder Cones are a rich source of humic and tannic substances beneficial for aquarium health. They gently lower pH, improve water clarity, and create a natural blackwater environment ideal for many tropical species.

These cones help inhibit harmful bacteria and fungal spores, making them especially useful during breeding by protecting eggs and promoting spawning readiness. Shrimp and small fish also enjoy grazing on or hiding among the cones, supporting natural behaviours.

Key Benefits:

• Natural source of humic and tannic acids
• Promotes plant growth and crystal-clear water
• Supports fish health, breeding, and egg protection
• Ideal for shrimp and small bottom dwellers

A simple, effective way to bring nature’s balance into your aquarium.
