Plant fertiliser for freshwater aquariums

Primary care for vigorous plant growth: fertiliser tablets for freshwater aquariums
Vigorous plant growth, no deficiency symptoms thanks to minerals such as iron, potassium and other trace elements
Optimal, intensive leaf colouring thanks to ideal iron concentration
Optimal promotion of plant growth means less algae growth. No phosphates and nitrates
Package contents: 1 packet FerroTabs, 30 tablets. Use: 1 tablet/25 l water for initial dosage and 1 tablet/50l water for redosage every week

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

Freuqently Asked Questions (FAQ)

I would like to fertilise my plants with your product and change over completely. How do I go about doing that?

Generally, one should never change plant fertilizers abruptly. The fertilizers from different manufacturers have somewhat different compositions in terms of trace elements. This may cause temporary nutrient changes. It is best to change over in 3 steps:

1) Reduction of the old fertilizer by 1/3; replace this with 1/3 of the new fertilizer. Wait approx. 3-4 weeks and observe the reaction of the plants.

2) Reduction of the old fertilizer by 2/3; replace this with 2/3 of the new fertilizer. Wait approx. 3-4 weeks and observe the reaction of the plants.

3) Complete discontinuation of the old fertilizer and change-over to the new fertilizer.

It is important to observe the reaction of plant growth and, in addition, to check the iron content of the water at least 2x weekly. Whereas the value should never drop to 0, it should never exceed 0.2 mg/l if possible. However, short peaks are no cause for concern.

These measures should generally be carried out on a weekly basis, ideally right after a water change. This achieves better results than fertilizing in large doses at longer intervals.

Where did my algae come from?

Algae problems in an aquarium can never be traced to just one factor or general condition, and instead, are always the result of a combination of different factors, which include light, fertilization, water changes – specifically, how often and how much – feeding, fish population and, of course, the specific water parameters.

According to analyses that were performed over a course of a number of years, red algae, at least the common brush algae and beard algae, occur in descending order at the following parameters:

1) too little carbon dioxide (in relationship to 100 % of the measured tank); the pH level should be in the slightly acetic range, depending on the carbonate hardness, in every case.
2) elevated phosphate levels (over 90 %); phosphate limitation by means of JBL PhosEx ultra is often helpful here.
3) too little and too irregular fertilization (there should always be traces of iron at least).
4) insufficient water changes; a weekly water change of over 30 % is recommended for algae problems.
5) not enough fast-growing plants.
