Aquarium Gravel, Rocks & Sand
Finding the best fish sand and gravel to create the perfect aquarium for your new fish is a very important. The right substrate, or what is more commonly known as the aquarium rocks or sand that lines the bottom of your tank, can make a world of difference. Aquarium gravel or sand for your fish tank will enhance the look and feel of your marine habitat. Larger aquarium stones or gravel should be avoided. Choose a finer gravel, perhaps pea-size aquarium rocks, if you want to include freshwater plants. Fine gravel will provide the plant roots a more stable environment. Aquarium gravel comes in a variety of colors and particle sizes so there are many varieties readily available to match your tank decor. Depending on the size of your fish, you can decide what sort of gravel will work best for your aquarium. Sand is definitely better for tropical fish and gravel is best for cold water fish. Shop the best fish sand and gravel for your aquarium habitat here on Chewy.com and let the fun begin.

Frequently Asked Questions about Aquarium Gravel, Rocks & Sand
Can I use both sand and gravel in my aquarium?
You can use both sand and gravel in your aquarium, but many experts recommend against mixing them together. If you choose to use both, try putting them in different areas of the tank. Sand can sometimes cause problems in aquariums, particularly those with live plants. It can become compacted and strangle plant roots, and packed sand can make it hard for burrowing fish to hide. Sand may also not work well with under gravel filters, and too-fine sand may clog regular filters, as well.
How do you clean aquarium rocks and gravel?
You can clean aquarium rocks and gravel in two different ways, either with or without a gravel vacuum. If you have a gravel vacuum, the process is fairly easy, and your vacuum should include good instructions for proper use. If you do not have a gravel vacuum, remove your fish with half their water and store them in a clean, fish-safe bucket or extra tank. Then, dump the gravel into a bucket and use a showerhead or hose to rinse it thoroughly, draining repeatedly until the water runs clean. You can also use this method to clean large aquarium rocks, and new aquarium gravel should be cleaned this way before use, too. You can now reassemble and refill your tank with your fish, their old water and new dechlorinated water to maintain a healthy bioactive balance.
How deep should the gravel and sand be in a fish tank?
The gravel and sand in a fish tank should be just deep enough for aesthetics and proper function. A gravel depth of 2 to 3 inches is ideal for most aquariums, as this depth is enough to anchor plants and/or cover an under gravel filter. For sand, a depth of 1 inch is recommended for most tanks. Larger aquariums may need a slightly deeper substrate, with 3 to 4 inches of gravel or a 2-inch depth of sand recommended.
How often should I change aquarium sand?
You should not change aquarium sand too often, as it can last for a long time with proper maintenance. Changing substrate too often can also throw off the delicate balance of your aquarium and unnecessarily stress your fish. Many aquarists recommend changing the sand once a year or even less. However, very old sand may eventually start to alter the nutrient levels in your tank, so it's a good idea to replace your sand at least every 4 to 5 years.
