Nature at home – home for fish and plants
Fish need to be as comfortable in the aquarium as they are in nature. When setting up an aquarium and during partial water changes the aquarium needs sufficient bacteria to be biologically cleaned and to quickly break down harmful substances. Bacterial starters contain highly active beneficial bacteria which break down the ammonium/ammonia and nitrite as well as the fish excrement and other waste in the water.

Advantages of the JBL bacterial starters
Live autotrophic bacteria, breakdown of ammonium/ammonia and nitrite through active bacteria, breakdown of fish excrement and other waste.

Autotrophic bacterial strains grow somewhat more slowly than heterotrophic bacteria, but are faster and more efficient when breaking down pollutants (nitrification).

8 complementary bacteria cultures to break down protein, ammonium and nitrite.
Gradually start with the stocking of fish in newly set-up aquariums immediately after adding JBL Denitrol.

Opinions vary as to whether fish can be added as early as one day after the aquarium set-up. Microbiologists have observed that bacteria reproduce very slowly in a new aquarium when there is no water pollution (nutrition for bacteria). But if you add fish the next day without using a bacterial starter, problems with ammonium/ammonia can occur, because the bacteria reproduce too slowly to keep pace with the production of pollutants at first. When using JBL Denitrol (60 minutes after adding JBL Biotopol) higher quantities of bacteria are present. The next day, after THE FIRST fish have been added, there is food for the bacteria and they start to reproduce. This will make sure that there are always enough bacteria, so that neither ammonium/ammonia nor nitrite can become a problem.
