  • Where did my algae come from?

    Algae problems in an aquarium can never be traced to just one factor or general condition, and instead, are always the result of a combination of different factors, which include light, fertilization, water changes – specifically, how often and how much – feeding, fish population and, of course, the specific water parameters. _x000D_ _x000D_ According to analyses that were performed over a course of a number of years, red algae, at least the common brush algae and beard algae, occur in descending order at the following parameters: _x000D_ _x000D_ 1) too little carbon dioxide (in relationship to 100 % of the measured tank); the pH level should be in the slightly acetic range, depending on the carbonate hardness, in every case. _x000D_ 2) elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here. _x000D_ 3) too little and too irregular fertilization (there should always be traces of iron at least). _x000D_ 4) insufficient water changes; a weekly water change of over 30 % is recommended for algae problems. _x000D_ 5) not enough fast-growing plants._x000D_

  • Can I use the JBL PhosEx Ultra and JBL NitratEx simultaneously in an internal filter?

    In principle, the NitratEx and PhosEx Ultra can both be used at the same time. However, please bear in mind that this reduces the other filter media as colonisation surfaces for the filter bacteria, which may affect the work of the filter in eliminating ammonium and nitrite.

  • Where in the filter do I need to place JBL NitratEx?

    The perfect place for the nitrate remover pad is relatively far up in the filter so that you can quickly get to it again for reactivation. With the JBL CristalProfi external filters this means at the top in front of the filter outlet. At the inlet to the filter the pad would quickly become clogged with coarse dirt and this would reduce its performance. _x000D_ _x000D_ Make sure that a sufficient layer of filter floss (JBL Symec or Symec XL) is placed in front of the NitratEx. The pad is followed by a final layer as a cover layer in front of the filter outlet.

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).
