What I Looked for Before Buying
Before I bought it, I paid attention to a few important things. I wanted sand that looked good, was safe for my fish, and would not cloud the water too much during setup.

In my opinion, it gives the tank a more natural and polished look, especially if I want a dramatic aquascape.
