A quiet and powerful air pump for lots of oxygen with 2 air connections (JBL PROSILENT a300)

Diaphragm pumps, also called air pumps, pump air into the aquarium or pond. The air enters the water through air stones and thus increases the oxygen content. On the way to the water surface, oxygen dissolves from the air bubble in the aquarium water and at the water surface the air bubbles produce small waves which increase the water surface. The larger water surface can absorb more oxygen from the air than a calm water surface.

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.
