Abstract
A system for nitrate removal from aquariums, both fresh water and marine aquariums, by means of permeable polymeric beads which contain a combination of fermentative and denitrifying bacteria and a carbon source. Preferred beads are beads made from sodium alginate or chitosan. The bacteria, in the presence of the carbon source, are able to reduce nitrate to nitrogen gas. Bacteria which are not harmful to fish are used. The porous beads used in the process are novel and part of the invention.
