Tip of the Day – 7/23/2010


Barebottom aquariums, or aquariums without a sandy substrate, lack a major source of nitrifying bacteria. Sure, the live rock will serve as a bacteria-rich substrate, but sand has a much high surface area. To deal with the lack of substrate, you can have a remote sand bed or fill your refugium with sand. Or, if you completely want to rid yourself of sand, try some of the commercially availalbe media like Biopellets or something similar.
