- Is this gravel safe for shrimp and small fish?
- Yes. The rounded 2–4 mm pebbles are smooth and small enough for shrimp and fry to move over without injury. It is intended for freshwater tanks.
- How much area does one 10 lb bag cover?
- It lays a thin layer, roughly enough for a shallow bed in a small or nano tank. For a standard tank with a deeper bed, plan on more than one bag.
- Can I plant live plants in it?
- Fine-rooted plants can be anchored, but the gravel holds little nutrient. Root feeders do better with a soil or planted substrate underneath.
- Does it need rinsing before it goes in the tank?
- Yes. Rinse it in a bucket until the water runs mostly clear to remove dust and fine grit before adding it.
- Will it change my water chemistry?
- It is inert stone and does not buffer pH or hardness. It is meant for freshwater setups, not saltwater.
- Can I mix it with another substrate?
- Yes. It works well as a dark cap over a nutrient substrate or mixed with a lighter gravel for contrast.
- Where is the Aqua Natural Midnight Pearl Gravel cheapest?
- At Petsmart, for $25.19, as of our latest check.
