GEN K is a liquid potassium fertilizer for planted aquarium keepers who see signs of potassium shortage in their plants. The manufacturer describes it as a highly concentrated product based on substances of organic origin, intended to supplement potassium in the water column.
Why it matters
- Potassium activates plant enzymes, takes part in osmoregulation and in nitrogen metabolism, and supports branching and the formation of new stems.
- Deficiency shows first on older leaves, so the problem is easy to spot before growth slows across the whole tank.
- Typical symptoms include small dots in leaves that enlarge over time, often with a yellowish halo, stunted new growth and leaf drop.
- The supplier states a capacity of 40,000 l of water and gives an example of 400 days for a 100 l tank at the recommended dose.

Frequently asked questions
The most common sign is small holes in the leaves that start as tiny dots and gradually grow larger, often with a yellowish edge. New growth may come out stunted, and leaves may drop off.
The dose is one click per 100 liters of water, applied daily. If the tank holds a large number of plants, the manufacturer advises increasing the dose accordingly.
It is best to dose near the filter outlet, so the liquid spreads through the water quickly.
According to the manufacturer, 400 ml is enough for about 400 days in a 100-liter planted aquarium. The product is based on organic substances, which the manufacturer describes as highly bioavailable.
The manufacturer states that the bottle lasts a long time even with a heavy plant load, but a densely planted tank needs a higher daily dose than the standard one click per 100 liters.
