JBL PROTEMP b III
Modern substrate heating for freshwater aquariums to promote plant growth

  • 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

Product information

Water circulation
Aquatic plants grow better in the wild when they have access to seeping nutrition sources. The plants absorb their food from these sources. The gently warming undergravel heating causes the warm water to rise and the cold water, full of dissolved nutrients and minerals, sinks to the bottom. This creates a thermal water flow, which washes the minerals and trace elements directly to the roots.

Easy to install
When beginning to set up the aquarium, position the heating cable in even-sized loops (in the area where plants are to be planted) on the cleaned bottom pane. Using the slotted suction cups enclosed, fasten the heating cable. Bring the cold leads of the cable out of the aquarium and connect them to the power supply. The black markings on the cable clearly distinguish the cold lead from the heating cable.

Safe to use
The heating cable is silicone-covered and works with an energy-saving power supply with 24 V safety voltage for hazard-free use. The the power supply unit needs to be mounted in a well-ventilated, splash-proof place. The undergravel heating results in a slight warming of the substrate, but definitely needs to be supplemented with a heater thermostat (JBL ProTemp s) for warm water fish. The power supply units heat up during operation - this is normal and due to technical reasons.

Tip:
If you don't want to use the suction cups to fix the undergravel heating cable, you can also glue the heating cable with small "silicone drops" and then remove the suction cups.

FAQ
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.

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.

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.

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.
