Product information

Nutrition for aquarium plants
Healthy plants prevent algae growth. Healthy plants prevent algae growth, supply oxygen, remove pollutants, offer hiding places and reduce pathogens.

Heatlhy plants = healthy fish
For the plants to flourish the the following demands have to be met:
Light as an energy source for CO2 photosynthesis, nutrients and trace elements as growth promoters.

JBL fertilisers supply the plants with all main nutrients and essential trace elements. This way the plants can absorb all the required nutrients they need over the leaves and roots, and deficiency symptoms (e.g. iron deficiency) are thus prevented

FAQ
Why has my Ferropol turned from olive green or yellow to brown?

The colouring of Ferropol depends on the pH value. During production Ferropol is set to a pH of 4.5. Then the colour is olive green. During longer storage and especially when the bottle has been opened, oxygen from the air gradually penetrates the fertiliser, the pH rises and changes the colour towards a brown tone.

This has no influence on the effectiveness of the fertiliser and its ingredients. You can safely continue to use it.

I opened my bottle of JBL Europol two months ago, and now “crystals” have formed. Do I need to dispose of the bottle now?

The bottle of JBL Ferropol is not worthless. Please shake the bottle prior to using the fertilizer and apply it the same way you did in the past.

Our fertilizer has a relatively high concentration, so that individual nutrient salts may form crystals in exceptional cases. As soon as they are in the tank water, they dissolve again and are then as effective as before. The chelated fertilizer components are not affected by this.

If I am using JBL 7 pellets, does it make sense to also fertilise with JBL Ferropol ?

Yes, that will be helpful and may even be advisable, depending on the plants in the aquarium.

The JBL 7 Balls pellets are primarily intended for root feeding plants and supply the plants with nutrients through their roots. Using JBL Ferropol to fertilise through the water column is generally advisable, as all plants (the stem plants more than the root feeders) also absorb nutrients through their leaves.

Despite continuous fertilization with the JBL Ferropol refill pack I can’t detect iron in the required concentration and my plants are deteriorating. What is the reason ?

A decrease of a measured iron value is most certainly not the result of a changed formula in the JBL Ferropol refill bag. It is more likely to be a result of the conditions in the aquarium. Aquariums, meaning here the substrates, and the aquarium filters can gradually develop into iron traps, especially when phosphates in higher concentrations are permanently present in the aquarium. Here a regular maintenance of the filter is advisable.

Furthermore the plant consumption is not entirely calculable. Even when no changes are made, the plant mass increases through growth, which leads to a higher demand. These are all factors to bear in mind.

There’s more to fertilization than you’d think Part 2

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.

Fertilization is not just fertilization Part 1

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.
