Alder Cones 25g (45-55 pcs)

Alder Cones – Classic Aquarium Botanical for Shrimp Tanks, Blackwater Setups & Aquascaping

A staple in the aquarium hobby, Alder Cones are one of the most trusted natural botanicals for conditioning water, supporting shrimp health, and enhancing blackwater aquariums. Small but powerful, these cones release beneficial tannins and humic substances that help create a more natural, stress-reducing environment for a wide variety of freshwater species.

Key Benefits

• Rich Source of Beneficial Tannins
  Helps lower pH gently, promotes a healthy biofilm population, and supports natural behavior in soft-water species such as shrimp, bettas, tetras, rasboras, and nano fish.
• Perfect for Shrimp Tanks
  Alder Cones are especially prized by shrimp keepers. They encourage biofilm growth—an essential natural food source for shrimp colonies and baby shrimp.
• Natural Anti-Fungal & Anti-Bacterial Properties
  Hobbyists commonly use Alder Cones to help maintain clean, stable water conditions, especially in breeding tanks.
• Versatile & Easy to Use
  Scatter them across your substrate for a natural look, tuck them into leaf litter, or use them as part of a botanical-rich aquascape.
• Natural Variation in Size
  These cones vary naturally from tiny to medium sizes. Each 25 g bag typically contains 45–55 pieces, depending on individual cone size.

How to Prepare

A quick rinse is usually enough. For slower tannin release, add directly to the tank. For a darker blackwater effect, pre-soak in warm water.
