JBL Denitrol Bacteria Starter For Freshwater and Marine Aquariums Available In 2 Sizes

Adds millions of beneficial, autotrophic and pollutant-degrading bacterial strains to the aquarium water, making immediate fish stocking possible. Highly recommended after using medications or after a complete water change
Shake the bottle well, measure the right amount in the dosing lid and evenly distribute in the aquarium
Live bacteria cultures with enzymes for rapid pollutant degradation in fresh, brackish & marine water. The bacteria have been inactivated so that they don’t need food (NH4, NO2) in the bottles and do not produce NO3. Activation through water contact
It is no use simply waiting for a healthy bacterial population to grow in your aquarium, as hardly any beneficial bacteria will develop in a new tank without water pollution. Bacteria only react and reproduce when they have a lot of food (NH4, NO2).
Package contents: 1 bottle Denitrol. Use: 10 ml for 20 l water during the initial setup and with disease, 10 ml for 300 l water during water changes
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.
