Choosing Gravel for an Aquarium
January 26th, 2010 | by admin |Gravel is a popular choice for the bottom of an aquarium. When choosing gravel, make sure that the diameter of the gravel pieces is not so large that pieces of uneaten food can lodge between the grains of gravel. This will be detrimental to water quality in addition to making it difficult for the fish to eat the food. Gravel should be smooth without any sharp edges to avoid the chance of fish tearing their fins or tails. A medium coarseness of gravel is generally preferred when using plants, to avoid the roots becoming compacted while still providing a good anchor for the aquarium plants.
