FAQ

Do bio-filter balls for nitrate removal have to be replaced after a while?

No, it is not necessary to replace the JBL BioNitratEx filter balls for nitrate removal. The balls are broken down by the bacteria and the carbon source they contain is used for nitrate removal. After 6 months you’ll need to refill the missing quantity (1 ball per 2-3 l water). Please do not remove the remaining balls, as they serve to inoculate the newly added balls. Please note that the balls need to be embedded in a layer of fine filter fleece so that the smallest parts of the degradation do not get into the other filter material. In marine water, the additional use of activated carbon is recommended to avoid initial cloudiness.

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.
