Ferrdrakon BIO Water Plant Fertilizer

Ferrdrakon BIO Water Plant Fertilizer as ready-to-use solution or as refill pack

Full Iron Fertilizer with completely biodegradable chelator

Ferrdrakon BIO hardly differs in application from the classic EDTA-type aquarium fertilizers. However, since the chelator used here, unlike the hardly degradable EDTA and related compounds, is completely biodegradable, it is better to fertilize several times a week in smaller doses for optimal results. However, this had already proven to be advantageous in many cases with the classic fertilizers.
The newly developed formula contains all essential and some additional growth-promoting micronutrients. Apart from potassium and magnesium, no macronutrients are included, especially no nitrate and no phosphate. If required, however, you can supplement these specifically with our special macronutrient fertilizers Eudrakon N and Eudrakon P.

Another advantage of the new chelator system is that Ferrdrakon BIO is little or not at all affected by intense blue light and UV radiation. The supply problems often experienced with EDTA-type fertilizers using UV water clarifiers and in extremely brightly lit tanks can now be much better managed. If, despite these improvements, you still notice a particularly high iron consumption, Daydrakon will continue to be a pure iron fertilizer at your disposal.

Composition [in mg/l]

Potassium 4 000, Iron 1 300, Magnesium 1 000, Manganese 600, Boron 60, Copper 20, Molybdenum 20, Zinc 20, Cobalt 10, Nickel 10, Aluminium 8, Lithium 5, Tin 5, Vanadium 5, Chromium 3, IDHA, PAA, Benzoic acid, Citric acid

Dosage recommendation

2 - 4 times 5 ml per week and per 100 litres tank water content, depending on lighting, plant quantity and growth.

After setting up your aquarium, start fertilizing with 2 - 4 times 2 ml per 100 litres of water and slowly increase the dosage to the normal dose as the plants grow.
If you have already used another water plant fertilizer before Ferrdrakon BIO, you can also start directly with the normal dose.

To remove unused nutrients and excretions from fish and plants, we recommend a minimum water change of 25 % every 2 weeks. However, there is nothing wrong with more water changes.

Ideal iron content

0.05 - 0.1 mg/l (up to 0.2 mg/l with extremely strong lighting)

Operating range and storage life

Sufficient for 2 500 - 5 000 litres of water
