What is carbonate hardness? Why is carbonate hardness like life insurance for your aquarium? What is the difference between it and general hardness and how does carbonate hardness work in your aquarium?

How does the nitrogen cycle in the aquarium work? Why do nitrite values get too high and how can the value be reduced? Why adding salt is senseless.

Have you ever asked yourself exactly what makes up the logarithm of a pH value? Why does the pH value in our aquarium matter and how can we influence it?

When algae take over the aquarium, there are always one or two possible causes. In this video, biologist Heiko Blessin explains very clearly and comprehensibly why algae grow at all and what we aquarium enthusiasts can do about it. The topic of algae in the aquarium has never been explained in a simpler and more understandable way!

If a brown coating covers the substrate of your aquarium and looks unattractive, let’s hope it is diatoms! The alternative would be smear algae - and they are not as easy to get rid of as diatoms.

Based on our own experience in customer service and the many messages and questions we receive, we have put together the typical mistakes beginners may make. The experienced aquarist might well smile, but if they are honest, these are mistakes we all made at the start, aren’t they?

Think back to your childhood. Your bedroom was a small area for you to let your imagination run free. And unsurprisingly you felt like re-decorating and rearranging it at least every three weeks.

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!

Many aquarium owners think that the general hardness represents the total of all minerals and the carbonate hardness only a part of it. Then how can the carbonate hardness sometimes be higher than the total of minerals?

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.

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.

The carbonate hardness (not the general hardness!) contains components which stabilize the pH level. They prevent extreme pH levels and ensure the aquarium functions properly.

With the right products, aquarium care is not only easy, but can also be a lot of fun! The formulas that make up JBL products are based on intensive research and, especially with care products, their effects are not always immediately visible, yet in the medium and long-term they’ll result in a beautiful aquarium and healthy fish.

The three most important factors for your plant aquariums are the nutrient balance, the substrate and the lighting.

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.

If we transfer this Liebig’s Law of the Minimum to the aquatic field it quickly becomes clear how important balanced fertilisation is for plant aquariums.

Even if your fish have fallen ill, it is not too late. Nonetheless we want to save the fish from getting ill. About 90 % of all fish diseases are the result of a weakening of the immune system.
