Dennerle Plants Soil is rich in nutrients and is therefore particularly suitable for planted aquariums. In addition, Dennerle Plants Soil is an active substrate that lowers the carbonate hardness (KH) and stabilises the pH value (approx. pH 6-6,5, KH 0-2dKH). Many aquarium inhabitants and also many aquarium plants prefer soft, slightly acidic water as in their tropical habitat. Dennerle Plants Soil is a natural product and consists of 100% valuable clay minerals. For filter bacteria, the porous 2-3 mm grains offer an optimal colonisation area to promote biological filtration. Dennerle Plants Soil substrate is ready out of the bag.
