We leveraged input from our veterinarians and artificial intelligence to identify key considerations to help you find the best aquarium gravel.
We scanned thousands of customer reviews and ratings and scored each product based on its performance against each of the key considerations. We then considered how popular a product is with Chewy customers and combined that with its key consideration scores to create the list of the best aquarium gravels.
Key aquarium gravel considerations
Grain Size and Texture
You want to ensure the gravel is comfortable for your fish to swim around and won't cause any harm, plus the right texture can help with water circulation and prevent debris from getting stuck.
Color and Clarity
The color and clarity of the gravel can greatly impact the aesthetic of your aquarium, and some colors can even enhance the natural beauty of your fish, so choose a gravel that fits your desired look!
Water pH and Chemical Neutrality
You don't want the gravel to alter the pH level of your aquarium water, which can be harmful to your fish, so look for gravel that's chemically inert and won't affect the water's chemistry.
Cleaning and Maintenance
Some gravels are easier to clean than others, and you want to make sure you can easily remove debris and waste without disturbing the gravel bed, so consider a gravel that makes maintenance a breeze!
