This is the general purpose variety that is best for mixed community tanks or ponds, but can be used in almost any aquarium except Marine Fish, African Cichlids, Arowana and Discus.  (It is better to select the specialized version that best suites these aquariums with special needs.) It creates an ideal stable balance of trace elements and minerals in the water either by adding minerals and trace elements, or absorbing them as needed.GEO LIQUID makes it easy for anyone to keep fish.  However, we advise everyone, if they want the best results, to use the version of GEO LIQUID specifically made for the particular kind of fish they keep, especially if they want to breed them. 

      GEO LIQUID is 100% natural and will do no harm to the fish, even if more than 2 versions are used at the same time.  It creates ideal conditions to bring out the brilliant colors that many tropical fish display when they are healthy and living in a stress free environment.
