Are fertiliser pellets (JBL 7 Balls) harmful for my invertebrates such as shrimp and crustaceans?

JBL 7 Balls are harmless to shrimp. It's worth noting that the commonly held notion of shrimp being sensitive to copper is not correct. What is true is that shrimp even need copper urgently as a trace element for their blood pigment (haemocyanin). When using a standard fertiliser, one must overdose 80-100 fold in order to reach the ranges that are dangerous for shrimp, or a copper overdose as applicable. The situation is quite different when it comes to copper-based medications or algae control products, as these have much higher doses.

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.
