Description

These alder cones are harvested along the streams of the north Black Forest in southwestern Germany. They belong exclusively to the Black alder. The ripe cones are picked directly from the trees in autumn. They then get air-dried. The cones are not picked from the ground, so an optimal quality is ensured.
Ripe alder cones are small, woody fruit stands of the Black alder and are a classic natural material to improve the water quality in the aquarium. For example, they are traditionally used to prepare biotope-compatible water for fishes from blackwater habitats.
Alder cones are rich in active substances such as tannins and renowned for their anti-bacterial and fungicide effect.
In addition, the cones are interesting for the natural aquarium design. Black alder trees typically occur on watersides and in swamps, therefore their cones are often found in natural waters in Europe. Especially in biotope aquariums, alder cones contribute to a natural appearance of the setup.

Features

  • Alder cones make the water lightly acidic (lower the pH value)
  • They lower the germ density and hinder infections with bacteria or fungus naturally
  • Release humic substances, colouring the water brownish
  • They improve the well-being of the animals and make the moulting of shrimps easier
  • Provide substrate for biofilm that is grazed by shrimps
  • Decoration material for a natural, biotop-like appearance of the setup
  • Also available as XXL version with extra large cones

Usage

1 alder cone for about 20 l water. In the XXL version, one cone is sufficient for up to 40 l of water.
The duration of effect lasts several weeks. Old cones may remain in the water for decoration.

Content

Alder cones, dried, in a resealable zip bag for ideal stock-keeping. For the XXL version, extra large cones are selected.
100 % Black alder cones (Alnus glutinosa).

Genau was ich erwartet hatte.. gehen relativ zügig unter, vielleicht ein paar Stunden oder so. Sehen halt nicht so riesig und störend aus wie die Seemandelblätter :)
