Scapers Soil is an active substrate specifically developed for aquaria. It creates slightly acidic soft water like that in which most tropical animals and plants live. Scapers Soil is ideally suited to plant aquaria especially aquascaping and shrimp aquaria. Scapers Soil consists of up to 100% natural raw materials. Made from various carefully chosen natural soils it supplies all the essential minerals and trace elements that aquarium plants require each day. The irregularly shaped grains with a diameter of 1 to 4 mm give the substrate a particularly natural effect.
