Factors to Be Considered When Choosing an Aquarium Gravel

Suitable environment

There are different water environments and gravels made for each environment. Although there are gravels that can work in both fresh and salt water, you can choose to buy the one that works specifically for your water. Putting gravel that works in freshwater, in salty water can cause some harsh chemical reaction. Ensure that your chosen gravel suits the water environment.

Gravel design

Aquarium gravel is basically used to beautify the water tank or support life growth in it. If you want your aquarium to be colorful, choose gravel that has different colors and polished smoothly. There are natural and artificial stones. Artificial stones might be so colorful and fascinating but it is mostly coated with a chemical. There are natural stones that are fascinating and beautiful; it is rarely coated with chemical and will not change the water acidic level. In essence, ensure that gravel complements your water tank and not just make it congested.

Gravel depth

After choosing the gravel to buy, you need to know the depth of the gravel need in the water tank. When purchasing gravel, keep in mind the quantity of gravel needed for each gallon of water. So, look at your tank size to know how much water gallons it can hold; then determine the number of bags of gravel to purchase. However, in determining the depth of the gravel, you need to consider the size of the gravel stones. Gravel with bigger stones will not require many bags as those with smaller sizes.

An additional thing to consider is your budget. There is expensive and cheap gravel out there. I know you will want to choose gravel with the lowest price, however, do not compromise quality because of cost. You can still afford relatively cheap and good-quality gravel. Also, it is recommended to choose gravel that is non-toxic. Go for natural gravel; it is safe and does not harm the life in the tank.
