How Do You Pick Fish Tank Gravel?
Picking your fish tank gravel is an important part of setting up an aquarium that is pleasing to the eye and comfortable for your fish. There are many types of substrata to choose from. Give some thought to what type of animals you will keep in your aquarium. Saltwater animals have different environmental requirements from freshwater animals. An aquarium supply store employee should be able to help you with this, but it is always a good idea to do a bit of research before going to the store so that you will have a basic knowledge of what you will need when you get there. Purchase aquarium gravel for freshwater animals that do not need to dig or burrow into the substrata. It will not change the alkalinity of the water, and it is an excellent filtering medium for bottom or under-gravel filters.
