Product features

  • An undergravel heating cable provides a natural-like thermal flow through the substrate and thus promotes the transport of nutrients to the roots
  • Easy to install: place the heating cable in loops on the bottom panel of the aquarium, fasten with the suction cups
  • The rising, heated water causes the colder water to flow in and thus ensures water circulation IN the substrate. In this way, the substrate also becomes a natural aquarium filter
  • Large cross-section of the heating cable for more power, 24 V safety voltage against hazards, high-quality power supply unit, spring clips allow mounting without tools
  • Package contents: untergravel heating cable for aquariums, incl. electr. transformer, heating cable with cold and warm conductor, suction cup attachment

Any further questions?

You’ll find answers to the most frequently asked questions in our FAQ section. If you can’t find what you’re looking for here, please don’t hesitate to contact us directly – we’ll be happy to help.

  • Can I use the nutrient powder if I have installed an underfloor heating cable?

    Yes, Volcano Powder can be used despite a bottom heating cable, as it is only applied thinly and does not completely cover the cable. The substrate above should be porous and coarse enough to allow water to circulate.

  • Why is the heating cable not getting warm?

    The floor heating cables of the JBL ProTemp b floor heating systems heat via radiant heat. If you lay these cables openly on a table, you will not be able to detect any warming by measuring the temperature. Only when the cables are installed under a layer of substrate will the substrate begin to warm up.

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.
