Řešení problémů pro akvária a rybníky


Výzkumem kupředu

Aby byl vývoj produktů spolehlivý a kvalitní je vždy nutná dobrá výzkumní základna. To je důvodem, proč ve výzkumných centrech JBL pracují biologové a proč JBL výzkumný tým pořádá pravidelné expedice (po celém světě) do přirozených biotopů zvířat, kde zkoumá nejen prostředí, ve kterém žijí, ale sleduje i chování a přirozené zvyklosti zvířat. Je to jediná cesta k vývoji kvalitních produktů, jež zvířata potřebují.

krmení ryb

The nutritional requirements of fish can differ as much as between dogs and hamsters. Here you will find comprehensive information on this important chapter about the feeding of aquarium fish.

Problémy s akvárii

Are you faced with algae problems or don’t your aquarium plants grow well? Is the water cloudy or are your fish ill? Don’t your water parameters correspond to your expectations? Our team of experts has thoroughly analysed the problems that occur in the aquatic field and offers you solutions which really work.

Vodní želvy

Turtles and tortoises are among the most popular of all terrarium animals and are despite (or even because of) their slowness absolute favourites for children too! A few points need to be remembered when keeping turtles, so that the animals feel comfortable, stay healthy and maybe even reproduce. We will give you tips and hints for their care.


Lighting is THE key to good terrarium keeping. Do your animals need only light, or do they need heat and UV? Here are the answers.

Biotopy data

We have visited the biotopes of terrarium animals and documented the biotope data. Here you will find all the data collected from all over the world.

Problémy s řasami

Why are algae a problem? What algae species can be found in the pond and how can you combat them effectively and for the long-term?

Nemoci ryb

In case your pond fish fall ill, we will show you which disease it is, and how to combat it reliably here.

Péče o jezírko

The different seasons (at least in Central Europe) require different care measures. Even in countries where there are no cold winters with minus degrees, factors like rainy seasons, dry seasons or perhaps a summer with particularly high temperatures all play a decisive role for the garden pond.


Inaccurate water tests – or did I do something wrong after all?

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 Biotope Aquarium: Africa - Nigeria

The region of the Lower Nile is the home of one of the most popular dwarf cichlids in aquatics: the kribensis, also called purple cichlid.


Pond guide: you ask, we answer!

We would like to give you the opportunity to ask technical questions about your pond. Are you interested in water tests and don’t know which water values you need to keep an eye on?


How much fertiliser does your aquarium need?

We are often asked: “How much fertiliser do I need for my aquarium?” On all product packaging you find dosage recommendations which give you initial information on how to start the fertilisation.


From ProFlora CO2 system owner to tester, free of charge
