  • Can I operate two coolers with one ProTemp CoolControl?

    The ProTemp CoolControl is connected between the power supply and the ProTemp Cooler. It is therefore not possible to connect two coolers to one controller. Each Cooler needs its own controller.

  • Why don’t the CO2 bubbles dissolve after reinstallation / cleaning?

    After reinstallation the bubbles move only haltingly through the diffuser and sometimes merge into large bubbles. The device needs approx. 48 hours to set up! After that a bio-film will have formed on the surface of the device, allowing the bubbles to rise freely upwards. After the running in time the required bubble count will adapt itself for your aquarium.

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.

A notification makes it possible to inform the user about an event outside the context of a website, such as a new blog post, a competition or a voucher.

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.
