Leonard Campbell –
I used this in my freshwater aquarium and it holds the substrate well. The blue color is vibrant and the material is stable. No issues with fish or plants so far. Good quality and reliable.
Irene Slater –
Works well for my terrarium setup. The aggregate stays in place and doesn’t break down quickly. A bit coarse for fine sand, but perfect for drainage.
Adam Randall –
Great for planters. Easy to mix with soil and doesn’t clump. My succulents are thriving. Non-toxic and safe for indoor use.
