Product information

Correct and long-term algae control
Excessive algae growth always occurs when a surplus of nutrients (phosphates and nitrates) are present in the water. That’s why long-term algae control always works in two steps: First the anti-algae agent JBL Algol fights the algae and then the nutrients are irreversibly bound. JBL PhosEx ultra or JBL PhosEx direct are very well suited for this. Algae-eating animals, such as sucker catfish, shrimps and snails can also be a great help.

FAQ
Is JBL Algol harmful for my shrimps?

Negative effects of JBL Algol on freshwater shrimps cannot be ruled out, especially on sensitive dwarf shrimps.

In what intervals can JBL Algol be dosed ?

We recommend an interval of 7 days when dosing JBL Algol again. Please ensure that a water change of 50-70% is carried out before each dose.

Please note that we cannot rule out adverse effects on aquatic plants after repeated applications. Furthermore JBL Algol does not eliminate the cause of emerging algae growth. For this please examine the care and maintenance of your aquarium.

How do mosses react to JBL Algol?

When dealing with mosses, one must always reckon with sensitivities to Algol, depending on the species, with this always applying to moss balls. Midget shrimps can also exhibit a sensitive reaction to Algol; our experience varies according to the species. The general water parameters are also important.

I have a lot of algae in my cichlid tank. Unfortunately, one-time treatment with JBL Algol did not have any noticeable effect.

With reference to algae in cichlid tanks. That is a permanent problem, because there is always an excess of nutrients in aquariums with few plants. It may be necessary to add more doses of JBL Algol, more or less at weekly intervals. Please make sure you always carry out a 50 % water change beforehand and ensure the aquarium is well aerated.

Can I kill off blue-green algae with JBL Algol?

Blue-green algae, that is quite a complicated matter.

As is generally known, blue-green algae are bacteria. They photosynthesise, just like plants. Blue-green algae are among the oldest organisms in the world. They would have been extinct a long time ago if they didn’t have a few special properties. For example, they influence the medium on which they colonise to their own advantage, i.e. manipulate the environmental parameters (which only very few organisms are able to do). This property has secured their survival. In their natural surroundings, blue-green algae are absolute niche inhabitants, which are always inferior to other organisms in competition.

Blue-green algae need light and nutrients, just like plants.

Blue-green algae, though, also need a substrate for colonisation to grown on. They are inferior to "normal" biofilms both in nature and in an aquarium and can only spread if the “normal” biofilm has been destroyed and has partially died off. Then they colonise quickly and consequently grow over the “normal” biofilm. As they change the water parameters under their own film, the normal biofilm dies off expansively, and the blue-green algae aquarium is born.

Algaecides are only effective against blue algae to a certain degree.

The only effective method currently known is deprivation of light, meaning full deprivation, to which they exhibit a very sensitive reaction.
