We’ll show you all the different aquarium substrates, from sand to coarse gravel, and list their advantages and disadvantages.

What makes for ideal plant growth? All the factors for good plant growth: light, LED, tubes, fertilisation, fertilisation quantity, fertilisation monitoring, influence of water conditioners, chelated iron.

If your plants aren’t growing perfectly in the aquarium, this video will help you. Biologist Heiko Blessin explains clearly and comprehensibly what is necessary for perfect plant growth in the aquarium.

You probably had this the last time you set up an aquarium. "Sand or gravel?” you wondered. “Or maybe soil? Or there’s that coarse volcanic rock?”

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.

Especially when new to the hobby, a lot of aquarium owners ask: Do I need real aquatic plants or is it enough to use plastic plants which can be easily cleaned?

Cat and dog owners know this well. A treat here, a toy there and small gifts for the pets. But what’s the best and safest way to pamper your fish with a few extras?

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.

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.

Have you ever had the chance to see how big the difference really is between a plant aquarium with and without CO2 fertilisation?

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

The subjects of plant care and fertilisation can sometimes take on a philosophical element. There are a lot of approaches and a lot of them can lead to success. It is important that your chosen approach suits your aquarium.

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.

Simply put, Liebig’s Law of the Minimum states that the growth of plants is limited by the scarcest resource. Adding a nutrient which already exists in abundance does not influence the growth.

Unlike in natural waters, aquariums with fish mostly have a surplus of nutrients caused by feeding and the resulting fish excrement. Thus nitrates and phosphates in large (often too large!) quantities are available for the plants.
