Substrate Additives for Plant Aquaria

Clay has completely special and unique features that make it predestined for use as substrate for aquarium plants. It has similar features to an ion-exchanger, and because of this it guarantees an even supply of nutrient substances, in that it holds back when excess is there, but gives-up when a deficit is present.

Our soil additives contain clay as the primary component.
