Blackwater Alder Cones 20pk
Alder cones are the beautiful, seed-bearing catkins of the Black Alder tree (Alnus glutinosa). Resembling miniature pine cones, these all-natural botanicals are highly prized by aquarists for their powerful water-conditioning properties. If you are looking to create a authentic blackwater environment, Alder Cones are one of the absolute best products available for staining your water a rich, beautiful amber tone.
Beyond their aesthetic appeal, Alder cones possess natural antibacterial and antifungal properties, making them an excellent addition to any freshwater system. As they settle into the aquarium, they serve as a perfect structural matrix for nutritious biofilm to develop, providing a continuous foraging ground for shrimp and grazing fish. Furthermore, their intricate shape offers excellent, secure hiding places for tiny fish fry and shrimplets.
-
Natural Water Conditioner: Rich in humic acids and tannins that help naturally and gently lower pH levels.
-
Shrimp Foraging Hub: Acts as a breeding ground for beneficial biofilm and can be safely consumed by shrimp as they slowly break down over time.
-
Antimicrobial Properties: Helps protect vulnerable fish and invertebrates from fungal and bacterial issues.
-
Boil Thoroughly: Because Alder cones "float like mad" when first immersed, you will need to boil them for at least one hour (sometimes slightly longer) to fully saturate them so they sink. This also helps control the initial, highly concentrated burst of tannins.
-
Go Slow: These cones leach a significant amount of tannins very quickly. Always introduce them to your aquarium gradually so you can monitor the effect on your water chemistry and inhabitants.
-
Average Size: Approximately 2.5cm to 3cm in diameter.
-
Origin: Organically and locally sourced, completely free of pests and pollutants.
Please Note: All of our aquatic botanicals are intended strictly for ornamental aquarium or terrarium use. They are NOT FOR HUMAN CONSUMPTION. DO NOT INGEST!
While all of our botanicals are thoroughly tried and tested, we always recommend practicing safe aquarium husbandry. Take the time to properly boil and prep the cones prior to use. Always introduce new botanicals slowly into your ecosystem to safely judge their effect on your fish, plants, and water parameters.
Note: This is a 100% natural product. Expect minor variations in color, size, and texture. Each cone is completely unique, and the product photo serves as a reasonable representation.
