Alder Cones (Approx. 4-ounce package)

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 alleged anti fungal and antibacterial properties. 

Our little Alder Cones are collected just for us in areas that are free from pollutants, insecticides, and pesticides by a great source who just happens to be a fish geek, too!

We recommend a starting quantity of about 5-8 cones for every 10 U.S. gallons of aquarium capacity, although there is no hard and fast rule about this. They can lower the pH of soft water surprisingly quickly, while imparting a nice brownish tint. Proceed slowly  and test your pH to gauge for yourself the effect that these little cones can impart to your aquarium water chemistry!  

Our Alder Cones are offered in an approximately 4-ounce package, which will  have anywhere between 130-180 cones (depending upon the physical size of the cones), for maximum value!

PREPARATION: We like to steep them in boiling water for about 20 minutes or so prior to use. This helps saturate them so they sink, and releases any surface dirt. 

ORIGIN: North America 


All of our aquatic botanicals are intended for ornamental aquarium or terrarium use only. Please use common sense and take the time to boil or soak all botanicals prior to using them, to reduce the possibility of problems. Always go slow when introducing any botanicals into your systems, so you can judge the effect they have on your fishes and plants. They are not intended for human consumption. DO NOT INGEST!



NOTE: The photo is for illustrative purposes. As these are a natural product, expect variation in the appearance of the cones that you will receive.
