Product description Congo River Gravel 7–15mm is a smooth, natural stone substrate ideal for freshwater aquariums, terrariums, and garden displays. The 7–15mm grain size provides a balanced blend of aesthetics and function—small enough for planted tanks, but large enough to support healthy water flow and prevent compaction. Supplied in a 20kg bag, it's well-suited for medium to large tanks or landscaping projects. The gravel is inert, making it safe for fish and plants without affecting water parameters.
