Product information

Ammonia and nitrite are toxic for fish. Biology and your filter should normally be able to keep the values within the problem-free range. This biological balance can be disturbed by medications, overfeeding and/or too many fish and the toxic substances listed can then occur in dangerous concentrations. Immediate action is urgently required to prevent fish loss!
The toxic substances are reliably and quickly neutralised by adding JBL Detoxol and rendered no longer dangerous. In addition you need to find out the reason for the formation of the toxins and how to remedy the problem.

Differences to other products:
Water conditioners, such as JBL Biotopol: water conditioners also neutralise chlorine, chloramine and heavy metals. But they can’t neutralise toxic nitrogen compounds, such as ammonia and nitrite.
Bacterial preparations, such as JBL Denitrol: JBL Denitrol is also able to remove ammonium/ammonia, but biologically, through bacterial degradation. Unfortunately this cannot be done in 10 minutes; it takes hours or even days. For the long-term function of an aquarium the bacterial water conditioner JBL Denitrol is the right product – for an instant emergency aid you need JBL Detoxol.

What happens when you use Detoxol?

It begins to work as soon as it is added to the water. The flow of the filter usually ensures that the water is evenly distributed throughout the aquarium within 10 minutes. During this process ammonium is bound to form a harmless compound. It is an organic compound and a derivative of NH3 in which two or three hydrogen atoms are replaced or combine to form compounds and are therefore harmless to the fish in the water.

High nitrite value - addition of bacteria and effects

When JBL Detoxol is used free ammonium is bound in the water, which provides immediate relief for the fish. This removal of ammonium also prevents any further nitrate from forming. Any nitrite already present is not bound. If you have high nitrite values, carry out a water change beforehand. A subsequent addition of bacteria will help you maintain a sustainable and biological removal of ammonium and nitrite.
