Aquarium Gravel, Aquarium Substrate

Deciding on your aquarium substrate (gravel) is fairly simple and straightforward.  For most freshwater aquariums you simply need to decide on a color of gravel.  You can add a little aquarium soil in places that you want plants to grow well in.   Most freshwater plants will actually grow fairly well just on gravel though.  In a hardwater (high pH) freshwater tank (mostly brackish water and African Cichlids) then adding an Aragonite substrate is recommended.  For saltwater tanks, a combination of Aragonite and finer live sand is the norm.   If you are keeping any type of shark or ray you will only want to use fine sand.

aquarilogo240x240The Aquaripure filter is a comprehensive biological filter which will completely process all organic matter and remove all nitrates in an Aquarium.  The Aquaripure uses beneficial bacteria to break down invisible organic matter and nitrates completely into Nitrogen gas which then escapes into the atmosphere. This same process is even used by some water treatment plants to make wastewater safe for human consumption and to clean polluted water. The Aquaripure does this in an extremely safe and controlled environment and after the water from the Aquaripure is aerated there is nothing left but pure, clean, crystal clear water.
