Without immediately adding animals, the cleaning bacteria used with JBL Denitrol / JBL PROCLEAN BAC will die within a short time due to lack of food. If the animals are added a few days later (contrary to the instructions), problems with ammonium/ammonia and nitrite will occur. Ultimately, the bacteria cannot develop due to the lack of food and will have already died. As a result, the ammonium excreted by the fish cannot be broken down. Since there are no bacteria present to oxidize ammonium into nitrate in two steps, a nitrite peak occurs despite the application. If the first fish are added immediately after the addition of Denitrol, the cleaning bacteria also receive food and begin to multiply. This is comparable to an unathletic person who starts exercising and first has to "train" to get in shape. This ensures that there are enough bacteria from the start and that neither ammonium/ammonia nor nitrite become a problem when more fish are added. Please always increase the fish stock moderately and only after a few days
The use of JBL Detoxol binds free ammonium in the water and provides immediate relief for the fish. At the same time, the removal of ammonium prevents the further formation of nitrite. Existing nitrite is not bound in this process. If nitrite levels are high, they should therefore first be counteracted by changing the water. The addition of bacteria then helps to remove ammonium and nitrite in a sustainable and biological manner.
Yes, this is necessary. The bacteria need some time to settle on the substrate and float freely in the water until then, which means that the UV-C rays would kill them. It is therefore advisable to switch it off for 48 hours.
Yes, that makes sense. Bacteria such as JBL Denitrol or JBL PROCLEAN BAC need some time to settle on the substrate and float freely in the water until then, so that the UV-C rays would kill them. It is therefore advisable to switch off the UV-C device for one day.
No, these bacteria are not harmful to humans. They cannot enter the air because nitrifying bacteria are substrate-bound and bound to an aqueous or at least moist medium.
The bacteria are contained in the products in a nutrient solution that meets the "minimum requirements," as a fully functioning metabolism would shorten the best-before date. As long as the bottles are in their original packaging and stored between 4-35°C, the best-before date is 18 months. If the liquid is clear, possibly with very small brownish flakes, the product is intact. Only a very faint odor is noticeable. If the liquid smells like rotten eggs or contains black flakes, the product is defective.
To answer this question, you need to know the current nitrite level and how it has developed over the course of approximately 4 hours after feeding. High nitrite levels can inhibit bacterial nitrite degradation. In this case, we recommend the following procedure: 1) Perform a water change depending on the nitrite level; if it is higher than 1.0 mg/l, change at least 50% of the water to reduce the current nitrite level. 2) Add a high dose of JBL Denitrol to the aquarium, approx. 250 ml per 150 l of aquarium water. Aerate the aquarium or adjust the filter outlet so that it circulates the air accordingly. The whitish cloudiness caused by the bacteria will settle within a few hours and the bacteria will then quickly begin to process the ammonium/ammonia and nitrite.
No, feeding should be kept to a minimum and should not exceed 25% of the usual amount. The bacteria adapt to the current water load and should therefore not be overwhelmed. A slow increase allows the bacteria to adapt to the environment.
New aquariums can be stocked immediately after adding JBL Denitrol at a rate of 1 cm of fish per 2 liters of water. After 14 days, the fish stock can be increased.
With Denitrol, you can take up to 5 times the recommended dose.
