Alder Cones – Natural Aquarium Botanicals

Create a beautiful, natural freshwater aquarium with our Alder Cones. These dried botanical cones gradually release natural tannins into aquarium water, producing a golden to amber tint and helping recreate the appearance of natural blackwater habitats.

Perfect for Betta aquariums, shrimp tanks, and botanical aquascapes, alder cones add natural texture while providing surfaces where beneficial biofilm can develop.

HOW TO USE

  1. Rinse: Gently rinse alder cones with clean, dechlorinated water before use.
  2. Add: Place cones directly into your aquarium. They may float initially before becoming waterlogged.
  3. Allow Tannins to Release: Cones gradually release tannins, giving the water a natural golden or amber appearance.
  4. Replace as Needed: Leave cones in the aquarium until they begin breaking down or replace them when tannin release decreases.

Recommended Starting Amount: Begin with approximately 1 cone per 5 gallons of aquarium water. Adjust gradually depending on your desired tannin level and aquarium conditions.

WATER PARAMETERS & CARE

Alder cones can influence aquarium water chemistry, particularly in soft water with low carbonate hardness (KH). Monitor pH and other water parameters when introducing new botanicals.

PLEASE NOTE

  • Naturally dried botanical cones; not live plants.
  • Size, shape, and color vary naturally.
  • Tannins may tint aquarium water yellow, golden, or brown.
  • Effects on pH vary depending on water chemistry.
  • Not intended as a replacement for aquarium maintenance or medical treatments.
