The product pictures stand as examples. Stones are a natural product and no two rocks are the same. Each purchase will be comprised of an individual and unique selection of stones.
We would suggest using 10KG per 50L. For example, for a 100L tank use 20KG. An average piece weighs approximately 2-3KG. We aim to include a range of sizes and shapes.
