Black River Slate is a type of hardscape that isn't too commonly seen in the planted aquarium hobby. These flat stones are perfect for stacking cave structures or creating paths in the planted aquarium. Color tones are dark grey, almost black when submerged and provide lovely contrast against vividly colored aquarium plants. These stones are also easy to break apart for multi-use purposes and very ideal for wrapping your favorite aquatic mosses around them such as Riccia, Mini Pellia, Fissidens Fontanus, Christmas Moss and more. Alternatively, Black River Slate can also be used as a base hardscape for scapes that utilize intricate driftwood work.
