Wooden roots belong to the most natural decoration in your aquarium. There are very few natural biotopes (Lake Malawi and Lake Tanganyika) where no wood or hardly any wood is found in the water. Wood can be found in the waters of South America, Central Africa and Southeast Asia as well as in most Australian waters. These roots or branches are used by most fish as a shelter, because in open water they would be easy targets for predators. After buying a wooden root for your aquarium, test it to see if it floats or sinks. If it floats on the water surface, it needs to be tied or glued to a stone for underwater decoration. Please do not use metal parts or lead weights to weigh it down, as metals are toxic for your aquarium inhabitants. You can also soak new wooden roots in a separate bucket (no cleaning agent residues!) for a few days and then insert them into your aquarium. If the wood root turns your aquarium water brownish, you can remove the colour cast by filtering it through activated carbon (JBL Carbomec activ/ultra - depending on the pH value of the aquarium water).
