Running-in or initial phase
Here’s how to ensure your aquarium has the right start – the important running-in phase
Once your aquarium is set up, water has been poured in and the technical parts are running; only the microflora for it to work biologically is missing.
Sometimes it is recommended to wait just a few weeks, before adding fish and invertebrates. But this approach bears the following risk: If running in the aquarium WITHOUT fish and invertebrates, beneficial bacteria hardly develop and reproduce in the aquarium because without fish and invertebrates there is simply no water pollution. But if you add them from the beginning the reproduction of bacteria lags behind and the water values can become critical, even leading to deaths (ammonia and nitrite; for more details, see Parametry wody ).
We therefore recommend the following procedure with its guaranteed functionality:
At least 15 minutes after adding the water conditioner JBL Biotopol please add JBL Denitrol (shake well before using). After a few hours the containing bacteria will have become active and start to break down pollutants and to reproduce. Thus you can (and you should) start adding the fish stock the following day and increasing the number during the following days. As a consequence the bacteria are confronted with increasing water pollution and react by reproducing. At the same time the bacteria you have added prevent problematic water values (ammonia and nitrite values).
Attention: The use of antibacterial medicines, such as JBL Ektol bac Plus 250 will also kill the available beneficial bacteria. Therefore you will need to inoculate your aquarium again with bacteria after the treatment, as you do for an initial setup.
