        Product information

        Healthy fish and plants
        Fish depend on the right ambient temperature because, being cold-blooded animals, they are not able to adjust their own body temperatures. The vital functions of cold-blooded animals decrease with falling temperatures. The right aquarium temperature is therefore very important to ensure the animals maintain their food intake and guarantee a smooth continuation of all metabolic processes. Depending on the origin of the fish, the temperature they feel comfortable at, varies. With the JBL aquarium thermometer Mini you can monitor the temperature on a fine measuring scale with a 2 °C gradation. The thermometer has a length of 60 mm and a diameter of 5 mm. It is filled with non-toxic alcohol.

        FAQ
        Why doesn’t the thermometer stick to the pane?

        Please clean the pane thoroughly before you install the thermometer. Algae, biofilms and lime can prevent it from sticking. If the thermometer still doesn’t hold, there may be a problem with the suction cup. Due to a material defect some suction cups have bubble-like excrescences which prevent a correct hold. If you own such a suction cup, please contact our customer service, and provide a photo.

        The JBL thermometer or the JBL aquarium thermometer is broken. It contains a red liquid. What does the red liquid consist of and is it toxic?

        The thermometer doesn’t contain any mercury. The liquid contains an alcohol solution with colouring. It is non-toxic. Both ingredients are quickly broken down by the bacteria in the aquarium. Furthermore the diluting effect should be taken into consideration. The silvery pearls are an iron compound and are therefore harmless. Simply siphon them out of the aquarium.

        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).
