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.
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
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.
JBL FerroTabs as a Primary Iron Source for Plants
FerroTabs are water-column fertiliser tablets built around iron and the trace elements that drive vigorous growth and strong leaf colour. They dissolve into the water rather than feeding the substrate, so they suit floating plants, epiphytes like Anubias and Java fern tied to hardscape, and any layout where you can’t easily push tabs into the roots. Dosing is straightforward: one tablet per 25 litres to start, then one per 50 litres weekly.
Iron is the trace element planted tanks here run short on first, and the early signs, pale or yellowing new leaves, are easy to miss until growth stalls. Keeping iron topped up keeps colour deep and helps plants outpace algae for resources. There’s no added phosphate or nitrate, so you manage those independently through your stocking and feeding routine.
Dissolve a tab in a little tank water if you prefer even distribution in a larger setup. For diagnosis and dosing, see our iron deficiency guide and trace element dosing guide, and explore more plant supplements.
