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.

In this case, the following procedure is recommended:

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.

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.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
