Water treatment

Tap or well water are still far from perfect pond waters

In most cases tap water is intended to be suitable as drinking water for us humans. It needs to be germ-free – nothing else. In some regions it contains a lot of minerals (hard water), whereas in others very few (soft water). Because of the water pipes it can contain heavy metals, such as copper, lead or zinc which can be toxic for our water dwellers. In some countries and regions chlorine is added for its disinfection. No water animals can easily tolerate chlorine.

The copper rain gutter problem

If you direct rain water through copper rain gutters into your pond, the following happens: The rain water dissolves copper from the copper gutter and it enters your pond. Copper is not only a problem for invertebrates, it can also be deadly for fish from a concentration of 0.3 mg/l.

That’s why a water conditioner JBL BiotoPond is highly advisable. It neutralises the effect of chlorine and encloses (chelates) heavy metals so that they no longer pose a problem.

Acid rain

In regions with soft water and whenever rain water enters the pond, the mineral content of the water decreases steadily. One part of the minerals, the so-called carbonate hardness, ensures a stable pH value. If its content drops too, the pH level of your pond is no longer stable and fluctuates wildly. Since the pH value has a logarithmic scale, a rise from 7 to 10 in the course of the day means a thousand fold decrease of the acid components in the water. At night the pH value drops again and the animals again have to cope with a thousand fold increase of the acid components. You don’t have to be a biologist to see that this not good in the long run.

You can avert this problem by adding minerals. For regular applications JBL StabiloPond Basis is available for you. For an individual application after very heavy rainfall JBL StabiloPond KH is the right means.

Well water

Not every type of well water is suitable for pond water. This is the reason that a lot of wells are NOT used to source of drinking water. In agricultural regions herbicides (weed killers), pesticides (pest control agents), fertilisers (phosphate and nitrate), as well as some very high iron concentrations can accumulate in the groundwater (= well water). You can check phosphate, nitrate and iron contents reliably and quickly with water tests. Herbicides and fungicides are difficult to trace. Please test your well water in a mini aquarium with plants and microorganisms (not with fish!) before using it in the pond. This will quickly and clearly show whether it is suitable for the pond.

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.
