Are you planning for an algae problem in your pond?

It’s no joke: at the time of writing this, lots of pond owners are already laying the foundations for a big algae problem in spring/summer! The increasing hours of sunshine cause algae problems to burst into action. However, the cause is ALWAYS an excess of nutrients and NEVER just the light. A bottle of distilled and thus nutrient-free water in the blazing sun is good proof of this. Without nutrients, algae can never grow - even in the strongest light.

The algae and plants that die in autumn/winter release the nutrients bound in them into the pond water, and nitrates (NO3) and phosphates (PO4) are formed. A water test for the two algae nutrients immediately shows how high the water load is. In summer, when algae growth is strong, the nutrients are of course hardly detectable, as they are bound INSIDE the algae. Only when the algae die (even after using an anti-algae agent!) do the nitrate and phosphate levels increase drastically. With the low light incidence in winter, they do not lead to algae problems. But when the amount of light increases in spring, the table is richly set for the next generation of algae! If you bind off nutrients now, you deprive the algae of their nutritional basis and prevent them effectively! JBL happens to offer two highly effective nutrient binders, JBL PhosEX Pond Filter and JBL PhosEX Pond Direct , for pond owners with and without filters respectively. If there is any need...

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.
