  • After using JBL SilikatEx (rapid), the silicate level does not drop. The silicate test still shows a deep blue to black color, which means more than 6 mg/l silicate.

    A value of > 6 mg/l obtained in the silicate test means that more than 6 mg/l of silicates are present in the water. It is not possible to determine how much more silicate is present. It could be 10, 50 or even more mg/l of silicates. In many regions, tap water today contains silicate levels of more than 40 mg/l. More detailed information can be obtained from your water supplier or by diluting the water to be measured with silicate-free water, e.g. double-distilled water, before measuring. If osmosis water is used for dilution, the silicate content must also be determined. JBL Osmose 120 produces a permeate with 0.4 - 1.2 mg/l silicate from 40 mg/l silicate in the source water. With such high silicate values, the reducing effect of JBL SilikatEx can only be verified by diluting the water to be measured accordingly. 500 g of JBL SilikatEx binds approx. 5000 mg of silicate from the water. 400 g of JBL SilikatEx Rapid binds approx. 12000 mg of silicate from the water. Calculation example: 100 l aquarium with silicate in the initial water 50 mg/l: 100 l x 50 mg/l = 5,000 mg silicate.

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).
