JBL Expeditions: Water analyses worldwide 2002-2019

For more than 20 years now, we have been conducting expeditions almost every year and have been able to gather valuable knowledge about the waters from which our ornamental fish come. On our expeditions we have carried out numerous tests to gain a more precise understanding of the conditions under which our aquarium fish live in the wild. In this post we have summarised all our measured water values. From one of our first expeditions to Sri Lanka and the Maldives in 2004 to the Japan Expedition in 2019.

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.
