FAQ

How do I properly open/close the CO2/pH permanent test diffuser?

To open the CO2/pH permanent test diffuser (angled model with black stand) just pull at the transparent cover with a sharp tug. The lid fits very tightly to prevent the diffuser liquid from leaking into the aquarium. To easily close the CO2/pH permanent test 2 diffuser (round model with white back) we recommend lubricating the seals with JBL SiliconeSpray. It is advisable to attach the lid in a tilted position and to press firmly against the bottom for 3-5 seconds to make sure that the rubber seal slips inside. Otherwise you can repeatedly press in “pumping strokes”. This ensures that the seal does not slip off and the diffuser liquid does not escape into the aquarium.

Both instructions apply to all batches manufactured until 10/2016. Subsequent models are provided with a modification which reduces the described effect if problems occur.

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.
