Ordered this because it said it was 2-4 mm in size which is pretty typical aquarium gravel size I would think. What I got was a bag of black sand in which the particle size is less than 1 mm.

Split the substrate between this live aggregate and a sandy like lagoon stays nicely separated. Great for bedding aquatic plants or aquarium faux plants.

I am new to aquascaping and this stuff makes me look and feel like a pro! I was careful but minimal effort, started with seeds and my tank had sprouts within days. Thrilled.

Took an extra week then came damaged they promptly sent me a new one. The product itself is great the black makes a pleasant contrast to my sand in my aquarium. Will buy again despite the delay
