I used this in my freshwater aquarium and it provides a great base for plants. The stones are clean and stable. No issues with fish or plant growth. Good quality and consistent size.
Jane Vance –
Works well in my terrarium. The stones are naturally shaped and hold moisture well. A bit coarse for small plants, but suitable for larger ones.
Andrea Thomson –
Great value for the size. Easy to mix into the substrate. My aquarium looks more natural with this product. No discoloration or fish stress observed.
