JBL ProScapers can prove their case

For the perfect growth of their plants, aquascapers depend on water analysis. There is a 99 % probability that one substance will run out and lead to a deficiency if they guess the amount of fertilizer needed and don’t check it afterwards.

JBL has a ProScape test case containing all the necessary water tests. With it the enthusiastic plant lover can measure all the nutrients individually, based on the calculated consumption just one day after the fertilization (online fertilizer calculator on: microsites.jbl.de/ProScape/calculator), and can then precisely adjust the fertilization.

The JBL ProScape Testlab contains - in addition to glass cuvettes, thermometer, report sheets with a ballpoint pen, colour charts, 2 dosing syringes, dosage spoons and cuvette holders - the following tests: pH 6.0-7.6; iron, CO2 Direct, magnesium in freshwater, potassium, phosphate, nitrate, silicate and carbonate hardness. Biotope aquarists particularly appreciate the comparator system with the JBL water tests, because many biotope aquariums have slightly tea-coloured water which leads to accuracy problems. JBL water tests contain a comparator system, which takes the inherent water colour into account and therefore always leads to very precise results.

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.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
