Bacterial initial phase

Beneficial bacteria in the aquarium

Cleansing bacteria – millions of little helpers for your aquarium

In each biotope, even in your aquarium, beneficial bacteria take care of the degradation of pollutants and thus maintain the biological balance.

When does your aquarium need “bacterial aid”?

There are definitely situations where you need bacteria. These include:

Initial setup of your aquarium

Run-in phase

What do you need to consider during the initial phase (run-in phase) of your aquarium? When can you add fish?

Bacteria for the plant growth promotion

When setting up a new aquarium a very interesting and effective way to promote plant growth and to prevent blue-green algae (Cyanophyceen) is by inoculating the substrate with mixed bacteria cultures. These bacteria colonise the substrate immediately and thus prevent harmful bacteria (Cyanobacteria = blue-green algae) from doing it. At the same time they have the properties to supply soil-bound nutrients and minerals to the plant roots. These bacteria visibly promote plant growth! With JBL ProScape PlantStart JBL has such a product in its range

After using medications

A lot of medications, especially antibacterial remedies, such as JBL Ektol bac Plus 250 affect your bacterial flora. After completing the treatment, you definitely need to add a bacterial starter, such as JBL Denitrol . Then, after about 12-24 h, the biological pollution digestion is in full swing.

After cleaning the filter and when using a new filter

The majority of the cleansing bacteria live in your filter. After cleaning and, of course, when starting a new filter, you need to re-establish the bacterial strain. For this purpose JBL FilterStart has been developed, whose contents comply with JBL Denitrol , but has a higher concentration and is suitable for filter volumes up to three litres.

Water change

When carrying out a partial water change you remove a part of the beneficial cleansing bacteria and this needs to be replenished with a dose of JBL Denitrol in your aquarium water. Please always dose for the volume of water you have changed.

For problematic ammonium (NH4) and/or nitrite values (NO2)

In case the nitrite is measurable and/or the ammonium test indicates critical levels you should search for the cause, as described under Daily care , carry out a partial water change and add useful bacteria with JBL Denitrol . But also bear in mind that the bacteria in Denitrol need a few hours before they become active. This means that an improvement of the values can’t be expected AT ONCE but with a delay of several hours. Please also take into account that a water change can raise the pH value when there are high ammonium levels, changing a large part of the non-toxic ammonium into toxic ammonia. A cautious reduction of the pH concentration with JBL pH-Minus can solve the problem of a high ammonia level (NH3).
