If you take proper action now, by reducing the nutrient input and the existing nutrient sources, you can prevent algae problems in the coming year.

Maybe you’ve felt like this: nothing works, the pond looks disastrous and you just don’t know what to do.

Die Sonne knallt auf den Teich und Sie füllen täglich Wasser nach? An manchen Tagen fragt man sich, „ist das wirklich normal und nur die Verdunstung“?

Ask us your technical question and we’ll answer your question in the comments with our team of experts.

Granted, nobody really enjoys testing water. It’s time-consuming and sometimes you’re not sure which colour on the chart your water result matches. But water testing really can be lifesaving – at least for your fish!

A lot of pond owners neglect their regular maintenance and only react when problems occur and it’s often too late.

The car roofs are yellow, the windows dusty and on the water surface floats a yellow-green film of flower pollen and insects. Take immediate action, using preventive or immediate measures to make sure it won’t lead to problems.

Water changes have several additional benefits: potentially dangerous substances, such as nitrates and phosphates, are removed from my pond, minerals are added, and any colour cast in the water is reduced.

Our 15 expeditions have taught us something new: In natural waters nitrogens (ammonium/ammonia, nitrite and nitrate) and phosphates are ALWAYS scarce and below the limit of detection. Only when humans have an influence on the natural water, can nitrogens and phosphates be found.

A few algae in the pond do not pose a problem and even form a component of a healthy pond. But once the water turns green or „blanket weed“ algae become rampant, you then have a problem which needs fixing. Effective and longterm algae control consists of three steps.

While the title of the well-known book series may suggest the opposite, these books are actually full of excellent explanations for complicated facts. And that’s exactly what we also want to try and do, because the subject of water test/water chemistry puts a lot of people off.

The JBL plant care concept leads to vigorous and healthy growth even with the most demanding aquatic plants. JBL has all the components you need, whether it’s a fertiliser, a bottom substrate or a fully automatic CO2 fertiliser system.

Instead of comparing the colour change of the water on a colour scale, a second measuring glass with the aquarium water is put on the colour field of the colour chart.

It can affect every pond owner. But if you are careful you can avert problems before they occur. In the following article we would like to introduce you to the different types of algae you may meet in the garden pond:

Today I would like to give you an idea of what happens to koi in our dealers’ basins. Since our koi have just arrived half starved from Japan it is first the duty of our dealers to put the new arrivals in quarantine. First of all their general health is checked.

Here, for anyone who may have missed it or who wasn’t able to visit us there, is a short report of our successful trip to Japan.

In the aquarium scene we often hear people talking about “accurate” and “inaccurate” tests. But mostly they mean a rougher or finer scaling of the output values.

The water in your aquarium is outstandingly significant because it is a life-giving element for fish and plants.

Professional water analysis sounds very expensive. But the professional water testing in your aquarium or pond at home also works on a high level and above all it is simple and inexpensive.

The water level can drop by up to several centimetres a day. This means it has to be refilled once a week at the latest.

There has been plenty of heavy rainfall in Germany in the last few days. The ponds are full to the brim and the garden - and more - is under water.

We are constantly being asked by pond owners for advice about how to deal with the problem of algae carpets on the water surface.

The flowers are blooming and the allergy sufferers know it only too well: the pollen count! We can see the powdery yellow coating on our cars and on the forest paths. The pollen count and small leaves are floating through the air and reaching our ponds in huge amounts.

Many pond owners don’t realise this. That’s why they don’t react to algae growth until it’s too late. This is not only annoying, it makes it harder to achieve clear water for your dream landscape.

It’s getting cold slowly and the pond season is coming to its end. The leaves of the water lilies are dying and the sunshine hours are getting shorter. But in the pond there is still a lot happening. We will show you how to make your pond fit for the winter.

In the garden pond the pH rises to over 10 if the carbonate hardness is insufficient or non-existent. In unbuffered ponds the pH level can even fluctuate up to 4 pH value levels within one day.

Everyone knows this scenario. Just last week the pond was alright, then suddenly the algae came overnight. Why does this happen? It’s really very simple. You only have to keep in mind 2 factors.
