Alder Cones (50 pack)
Regular price $5.49 Sale price
Each order contains 50 alder cones.
The tiny fruit of the alder trees (Aalnus glutinosa and Alnus incana) has been widely utilized by aquarium hobbyists in Europe for some time. Betta and ornamental shrimp breeders are fond of the tannins released into the water by these cones, and their apparent anti fungal and antibacterial properties. Many ornamental shrimp seem to feed directly on the decomposing cones, so their use as a supplemental food source is yet another benefit! For the best effect, the dosage should be about 4-6 cones per 10 gallons and should be changed out every month or so. You could also leave them in the tank to decompose and this is fine as well as this is an all natural product!
