You should add about 1 pound of substrate per gallon of water. A safe bet would be 5 pounds of gravel for a 5-gallon fish tank. Roughly 20 pounds of gravel should be added to a 20-gallon fish tank.
If you want to add more substrate to your aquarium, it’s best to do so after the gravel has been added. If you don’t add enough substrate, your fish won’t be able to use the substrate properly, and you’ll end up with a tank that’s too small for the fish you’re trying to keep.

How many inches of gravel do I need for my aquarium?
If covering an undergravel filter, gravel needs to be at least two inches deep to anchor live or artificial plants. It traps a lot of algae if the tank is too deep. If the gravel is too deep, it will not be able to hold enough water for the plants to grow.
This is especially true if you are using a gravel filter that is not designed for gravel. If you use a filter with gravel in it, you will need to add more gravel to the filter to keep the water level high enough for your plants and fish to thrive.
How much gravel should be in the bottom of an aquarium?
It’s important to use the right amount of the substrate when placing it in the aquarium. Small to medium aquariums should have at least two to three inches of gravel or sand in the bottom. Larger aquariums should have at least three to four inches of gravel or sand.
If you are using a gravel substrate, you will need to add a small amount of calcium carbonate to the substrate to help prevent algae growth. You can also add some organic matter such as peat moss or compost to your substrate if you wish.
If you do not have a substrate of your choice, then you can use a combination of organic and inorganic materials to create your own substrate for your fish.
How much gravel do I need for a 10 gallon fish tank?
The calculation for how much gravel is needed for a 10 gallon tank is very simple. The rule of thumb is that you need 1.5 pounds of gravel for every gallon of water in the tank. For a 10 gallon tank, you will need 15 gallons of substrate.
So, if you have a tank that is 10 gallons and you want to add gravel to it, then you would need a total of 25 gallons. If you are adding gravel for the first time, it is best to start with a small amount and work your way up to a larger amount as you get more comfortable with the process.
How do I calculate how much gravel I need?
To measure the driveway in cubic feet, multiply the length by width by depth. For cubic yards, divide the total cubic feet by 27. One yard of gravel is equal to 1.13 tons, so you can divide it by 1.13 to convert it to inches.
For example, if you have a driveway with a width of 4 feet and a depth of 1 foot, then you would multiply 4 x 1 = 6 feet to get a cubic inch.
Is gravel necessary for a fish tank?
Perhaps the most important function aquarium gravel serves is biological filtration for good bacteria. The gravel bed is not sufficient to keep the aquarium safe from disease. Aquarium gravel can also be used as a natural filter for fish and invertebrates.
It’s a good idea to use gravel that has been treated with an anti-fouling agent, such as calcium carbonate, to help prevent the growth of algae and other organisms that can cause problems in an aquarium.
How much gravel do I need for a 29 gallon tank?
1 pound of regular aquarium gravel per 1 gallon of water is the rule for buying gravel for an aquarium. You should have a minimum of 30 pounds for a 30-gallon tank for each 1.25 gallons of water you plan to use.
If you have a larger aquarium, you may need to add more gravel to the tank to keep up with the water volume. You may also want to consider adding a layer of gravel between the bottom of the aquarium and the substrate. This will help keep the gravel in place and prevent it from sliding around in your tank.
How much gravel do I need for a 40 gallon fish tank?
For one inch of gravel, you’ll use one pound per gallon, and for two inches of gravel, you’ll use two pounds per gallon. A 40 gallon tank will use two, 20 pound bags for one inch and four, 20 pound bags per inch. For example, if you want to fill your tank with 1,000 gallons of water, then you’d fill it with four 20-pound bags and one 40-gallon bag.
If you wanted to do the same thing with 2,500 gallons, the total would be 6,400 gallons and you would have to use four bags of 20 pounds each for each gallon you’re going to need. This is why it’s important to know how much water you need before you start filling up your tanks.
How many fish can I put in a 55 gallon fish tank?
There is a bottom line. The one-inch-per-gallon rule is still in effect, so make sure you don’t exceed 55 inches of fish in a 55 gallon tank. Four or five bottom-dwelling fish along with a few other small fish, that’s roughly how it is. If you have a larger tank, you may need to increase the size of the tank to accommodate the fish you are planning to keep.
