Buy Aquarium Gravel



Aquarium gravel, or any other material placed on the bottom of the tank, is referred to as substrate. Beneficial bacteria reside in your aquarium's substrate and break down fish waste, leftover food, and plant debris to keep the water conditions healthy.

Soil is specifically used in planted tanks. If you do not plan on growing live plants in your tank, then you should use a different substrate. Besides, if you are just using soil because of the color, then you will be pleased to know that pebbles, gravel and sand are all available in varying shades of brown.


Generally speaking, if you unintentionally add a substrate into your aquarium that changes the water, you are going to have a bad time. Using play sand as a substrate, for instance, can introduce silicates into your water, which can then lead to an outbreak of brown algae.


Ugh! We have the worst water ever; pH over 10 & super soft. Plus it has radium 224 & 226, with half-life of 3/6 days & 1600 years respectively, cyanide and too much copper & lots of sediment. Thank you Oil Well Frackers! My grandchildren recently got a beta & Marimo moss ball; I knew I had to have one. I just emptied the 45 gal tank of a mixed crushed limestone & decorative gravel because I could not keep the pH down in a safe range and it was getting spendy with the chems. Then I realized this substrate was for my cichlids many years ago.


Because your gravel is already inside the tank, any extra substrate added is going to add thickness, giving you and your fish less room inside the tank. f you want to add aquasoil for growing plants, root tabs are an alternative option, allowing you to keep your existing gravel while providing nutritents to plants.


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.

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.


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.


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.


You should not change aquarium sand too often, as it can last for a long time with proper maintenance. Changing substrate too oft
