Ferrdrakon Evolution - The intelligent fertiliser system
Automatic - Dynamic - Every day
Every aquarium is unique, just like its nutrient requirements. Whether aquascaping or East African cichlids, community or old water tanks, the intelligent fertiliser system Ferrdrakon Evolution automatically adapts the dosage to the entire aquarium configuration. Factors such as planting, growth rate, lighting, stocking or filtration will not play a role in the future when adding fertiliser. This means that time-consuming water tests are no longer necessary.
Use
Please add the fertiliser sticks or nets to the fertilisers listed in the Ferrdrakon Evolution fertiliser calendar at the times indicated in the Ferrdrakon Evolution fertiliser calendar. Please always select the product variant first and then download the appropriate fertiliser calendar.

6 fertiliser nets for tanks with a capacity of 60 to 90 litres
Fully chelated, slow-release complete iron-potassium fertiliser. Contains no nitrate and phosphate!
Fertiliser calendar
A fertiliser net is placed in the filter during the specified weeks. After the 4th or 5th addition, the nets inserted up to that point can be removed.
Scientific basis
It is a well-known phenomenon that even aquariums designed and set up in largely the same way can develop completely differently. These deviations can be observed even if the starting conditions of systems only differ in the sub-atomic range. Such structures are scientifically described and researched in chaos theory using so-called fractal functions.
Our (planted) aquariums are also such chaotic systems and follow fractal laws.
Thanks to intensive research on aquariums in recent years, we know that there are interactions between chaotic systems and the dosing of substances. These interactions can be calculated and predicted using fractal mathematics.
Consequences for the application
After analysing hundreds of series of measurements in fertilised and planted aquaria, our assumption has been confirmed. The temporal course of the concentration of aquatic plant fertilisers is neither uniform nor completely irregular, but follows seemingly chaotic fractal patterns.
Attempts to control the nutrient concentration by means of measurements and targeted fertiliser additions unfortunately do not achieve the desired result. Over time, the probability of rapid, unexpected changes in concentration increases. The individual measurement becomes increasingly less important. Instead of stabilising the concentration curve, the fertiliser concentration then tends to jump from one concentration extreme to another.
Instead, apply fertiliser at the precisely calculated times of the fertiliser calendar units of the Ferrdrakon Evolution fertiliser system into the tank at the precisely calculated times on the fertiliser calendar. This ensures that the nutrient concentrations always remain within the desired range despite all fluctuations. As the natural nutrient fluctuations have already been taken into account when calculating the addition times, the system no longer builds up as with feedback. The concentrations remain within the desired range.

I have been testing it for 3 months and it works great, but I use it together with the complete liquid iron fertiliser as I have a lot of large plants in the tank. I will continue to use it, even if it is expensive.

Works perfectly
Ferrdrakon Evolution - The intelligent fertiliser system
I have been using DRAK fertilisers for quite a long time. First in liquid form. It works if you don't forget it. It's much easier with this fertiliser. Change the water, clean the external filter, and the fertiliser is already noticeable. Quickly add another bag and you're done! The plants grow like crazy, the red lotus overgrows everything. Even slow-growing plants are proliferating. But I also have a bit more light above the water surface. For me, it's the best fertiliser. Others may be cheaper, but will I have the same success with them?

It works
Ferrdrakon Evolution - The intelligent fertiliser system
So far everything is fine with the fertiliser. The plants are growing :)
The price is a bit steep and your replenishment calendar could slowly be updated to 2021 :)

Too complicated
Ferrdrakon Evolution - The intelligent fertiliser system
I have been using Ferrdrakon Evolution with fertiliser calendar for 3 months now. The growth of the plants could be better. This is due to the rather complicated fertilisation dates. I missed the right time and the plants thanked me with a pause in growth and lots of yellow leaves. I also don't know exactly when to take out the old bags and when to leave them in. Before this system, I had Ferrdrakon Power and was really happy with it. Unfortunately, this is no longer available. This variant of long-term fertilisation is simply too complicated!

A perfect fit!
Ferrdrakon Evolution - The intelligent fertiliser system
I have been using Ferrdrakon Evolution according to the instructions for a year together with other Drak products, the tank is maintained exclusively with Drak products: The plants grow more than luxuriantly. Since using the Drak products, the tank has been running reliably and with little maintenance. A definite recommendation!
