a sand bed in an aquarium can be very beneficial. First and

their seas and oceans. You will find your fish happier in the sand and even spawning in them, which could be a
delight to watch. Sand is not very difficult to clean too, if one does it in the right way. In fact, using sand in
an aquarium makes it look more real and the fish enjoy is more than a gravel bed.
Live sand is especially beneficial to the organisms in your
tank. Live sand is biological sand. It is pre-seeded with certain microscopic organisms such as bacteria and algae.
These organisms help to clean the water in the tank and also produce the chemicals that are present in natural
habitat. Live sand can be very expensive, such as live aragonite sand, but it is a very good option to have at the

of this sand are that it is smooth and sifts easily. It is very easy to clean during setup and maintenance, and it
is available very cheaply.
As the name suggests, coral sand is suitable for tanks that have
corals as their inhabitants. Since corals can change internal levels of the tank, such as the nitrate levels and
the pH values, drastically, it is wise to use this sand. Coral sand has a natural buffering action that can
maintain the chemical composition of tank water at optimal values.
Though this is not actually sand, it is sold as such. Black
beauty is actually solidified and powdered iron slag. It adds a contrast to the tank and is good for aesthetic
reasons. But the sand particles are sharp, so do not use this sand if you have fish that sift too much on the
