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

  • Why doesn’t the heating cable warm up?

    The substrate heating cables of the JBL ProTemp b series heat with radiant heat. Laying these cables on a table you wouldn’t notice any rise in temperature through temperature measurement. Only when the cables are installed below a layer of substrate will the warming of the substrate take place.

  • JBL ProTemp b10-60: What minimum grain size is needed for the substrate to prevent heat building up from the substrate heating cable?

    If you have sand, a substrate heating cable is not recommended. It should be used for gravel sizes of 1.5 mm and over.

  • Can JBL Manado be used with a substrate heating cable additionally, or would that lead to overheating?

    I don't see a risk of overheating as long as the substrate heating cable is installed properly with the spacers and is not placed directly on the glass pane.

  • May I use the nutrient powder when I have installed an undergravel heating cable?

    Yes, despite an undergravel heating cable you can use Volcano Powder because it is only applied very thinly and doesn’t completely cover the cable. The substrate above needs to be porous and coarse enough to enable the water circulation inside.

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.
