Product features
- 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

Despite JBL Denitrol, the nitrite level has not dropped.
In order to answer this question, we would need to know the current nitrite level and how it has developed in the course of 4 hours after feeding. If the nitrite levels are high, an inhibition of the bacterial decomposition of nitrite may occur. _x000D_ _x000D_ In this case, the following procedure is recommended: _x000D_ _x000D_ 1) Do a large water change in accordance with the nitrite level - at least 50 % if it is over 1.0 mg/l - in order to decrease the current nitrite level. _x000D_ _x000D_ 2) Add a large dose of JBL Denitrol to the tank, around 250 ml per 150 l of tank water. Aerate the tank or set the filter outflow so that it creates enough turbulence to bring in oxygen. The whitish cloudiness caused by the bacteria will disappear within a few hours and the bacteria will then quickly start processing the ammonium/ammonia and nitrite.

If I want to add live bacteria to my aquarium, do I need to switch off the UV-C device?
Yes, this would be useful. The bacteria, as for example in JBL Denitrol or JBL PROCLEAN BAC, need a little time to settle on the substrate. Until then they are floating freely in the water so that the UV-C radiation can kill them off. It is therefore recommendable to switch off the UV-C device for a day.
-
How many fish, shrimps or snails may be inserted after 15 minutes?
After adding JBL Denitrol into initially set up aquariums you can add 1 cm fish per 2 litres of water. You can raise the fish stock after 14 days.
-
May I feed the animals on a regular basis during the first three weeks?
No, you need to feed them very sparingly with maximum 25% of the usual amount. The bacteria are adapting to the current water load and may not be overstrained. A slow increase allows the bacteria a stable adaptation to their environment.
-
Can you overdose Denitrol?
With Denitrol you can add up to five times the amount of a dose.

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.
